Decent day at the pier today. Personally—1 Sand bass, 2 Thornbacks, 1 Lizardfish, 3 White Croaker, 2 Mackerel, 2 baby Grey Smoothhound and about 15 Salema, some of which were 6”-7” (which is pretty good size for Salema!) Saw a good-sized (about 3 feet) grey smoothhound landed and several undersized halibut. Salema were the rule today, as many people had several in their buckets. I did see one of the craziest things that I've ever seen today; these kids had “Pixy Stix” candy mixed with water and were injecting it into their bait and were smokin’ everybody on the pier. These guys were landing fish left and right! Their day did end abruptly, however, when after one of them landed a stingray and after being warned by yours truly about the stinger in the tail, one of them got stung in the wrist. I suggested they high-tail it home and gave them the first aid procedure for taking care of it. Memo to beginners: Stingrays are not toys, handle with caution!! Tight lines to all!

Subject: Dangeous Stingray

I just found text below on the Net when I was trying to learn about stingray. The tail of the stingray sounded deadly, going near one doesn't seem like a wise thing to do. Does swing its tail around like a creature from out of space? How do you make sure the tail doesn’t strike you? How do you distinguish it from the Bat Ray? Some detail information would be appreciated. Sam

STINGRAY
Phylum Chordata, Class Chondrichthyes. These possess a serrated bony spine at the base of the dorsal surface of the tail. An integumentary sheath discharges venom when ruptured. Most injuries occur when the ray is stepped on, the tail is thrust upward and forward and fired into the foot or leg. The venom is thermolabile (deactivated with heat) and induces severe vasoconstriction.
Symptoms: Intense pain is felt at the site; there is local ischemia (loss of blood supply), and edema. Edges are jagged, may contain pieces of spine and secondary infection is common. Systemic effects include salivation, sweating, vomiting, diarrhea, cramps, hypotension (low blood pressure), and cardiovascular collapse.
Treatment: Irrigate and remove remaining spine. Immerse in hot (50 C) water until pain subsides. Give local or systemic pain relief. Cleanse, debride and suture the wound. Give tetanus protection, infection prophylaxis and monitor / support cardio-respiratory system as indicated.

I've fished from California piers for nearly 40 years, caught hundreds of sting rays/and bat rays and never been stung. (1) Learn to identify your fish. Buy my book or another book that contains pictures and read the descriptions. (2) Be patient and careful when handling the rays. (3) I generally grasp the tail with a pair of needlenose pliers, cut off the stinger, and then remove the hooks before letting the fish go. The stinger will grow back in 6-8 weeks. (4) Check out the topic feature at the top of this page. When I entered in the topic bat ray I was presented with 26 different responses on the topic.

It seems that people are afraid of stingrays as they are sharks. For a bat ray/sting ray to sting you, its tail must move vertically, exposing the stinger. This usually only happens when someone steps on a ray, especially when wading at the beach. However, to be stung on pier is pretty rare. I think it is STUPID and a WASTE for someone to cut off a bat ray’s stinger, it increases your chance of being stung, and it does great harm to the fish. I seriously doubt that the stinger will grow back in 6-8 weeks, if ever. This is the fact that the stinger is made of cartilage, the same material its wings are made of, which don’t grow back. This just makes me mad, it reminds me of going to the pier and watching retards step on short halibut or rays, then throw the dead fish back!

Last year at Bakers beach, my uncle caught a small stingray, around 20lb.'s. I was helping him take out the hook, I thought I was stepping on the tail, but the tail managed to squirm out from under my leg, My foot was between the part that connects the tail to the body, and the left wing. I was wearing tuff shoes, and it STUNG me; hurt like a .B. The dagger went through my shoe, and scraped on my bone; it electrocuted me! I felt the electricity, and it injected venom through my leg. It hurt for a few hours; still have the triangular scar on my foot and, hasn't changed since the day it happened. It REALLY SUCKED

Posted by goatfish

Just try a little caution and common sense...A stingray can sting without warning, and it doesn't have to be a vertical whip of the tail. Personally, I like to turn them over on their backs while I'm removing a hook, etc. but I try to stay away from getting near the tail at all. If you cut off the stinger, it WILL grow back, much like your fingernails will grow back when you cut them. More often than not, people get stung by rays because they are not paying attention, or are intrigued by the stinger and want to touch it. I've yet to catch a ray where the stinger was not exposed, and they WILL sting you if given the opportunity. I've seen people get stung, and it is not a pretty sight. Just remember to be alert and use common sense.

Posted by Anthony

Anyone ever thought about cutting the line and leaving the hook? They will rust out quicker than the stinger will come back.

Posted by Ken Jones

I actually learned about the removal of the spine and its ability to grow back from visits to the Monterey Aquarium and Chula Vista Nature Center. Both places have petting pools with bat rays in them and allow kids to pet the bat rays. After talking to people at both places I discovered that they clip off the stinger so that the bat rays cannot sting the children. Apparently it takes 4-6 weeks for the spines to grow back because they have to do this little operation on a regular basis to prevent the spines from becoming dangerous. By the way, the bat rays, minus their stingers, are about the friendliest fish you will see.

Posted by Kanamit

Ken, You are correct - I learned this too at the aquarium. The problem is sometimes that the Barnies on the pier cut off the entire tail of the ray. If this is done I don't believe the tail and stinger can grow back. I've actually seen idiots cut off the tail and miss the stinger entirely - it's too bad these retards didn't get stung after thinking they cut off the stinger. I feel it is totally irresponsible to fish for a species of fish without learning a little about it first. It is fine to snip off the stinger but leave the tail alone! I have caught hundreds of rays and although I used to cut the stingers off I don't really bother anymore. If you are careful I don't believe it's necessary.

Subject: SF Bay —Bat Ray vs. Sting Ray

Had a few q's regarding the bay rays:
1: What's the diff. b/w bat rays and sting rays, and how can I tell?
2: What do you do when you catch one, use a gaff or net, and if you gaff it...where on the body should I do that if I will be taking the critter home?
3: Once caught, is there anything I should do to ensure a good meal eg. bleeding, or kill them somehow?
4: Yesterday I caught something that looked like a manta ray actually,,, I didn't get a good look at it because as I was pulling it up on the pier, it tore 20# test....could have been a halibut...
5: Which ones should I keep to take home and eat...sting vs bat ray; big one vs. small one.... and I know the wings are the good part... what about the body or tail? any help will be appreciated, dr.moe

Moe-Bat rays have very large heads, ear holes (I use these to grab them when I pitch them back in the water), and are brownish-black on top and white on their bellies. I have never caught an actual stingray in the S.F. Bay (where I fish) but I have caught a thornback ray or two. When you get a bat ray out of the water, they will huff and snort quite a bit. They have big cow-like eyes. Funny thing about a bat ray, they’ve got black eyes, lifeless eyes like a doll's eyes.
With large fish caught in bay waters, the sooner you clean the fish the better. This immediately rids the fish of toxins and parasites in the innards.
I have either hoisted it up by the ear holes or used a hoop net to bring it up from the pier. I don't use gaffs, at all.
I doubt you caught a manta ray, they are off shore species and usually do not eat large baits.
A good basic rule to follow is the larger the fish, the longer it has been swimming in the water, and if that water is subject to pollution, therefore the longer it has been absorbing said pollution. I personally don't keep striped bass over 28 inches or so, for an example. Remember that bat rays have no bones, just cartilage and fat, in addition to muscle. A flat piece of cartilage runs straight through the middle of the wing, and if you fillet the meat on either side of this, you should get four nice fillets. I personally would not eat a ray when there are perch, bass, or sturgeon to be caught, but many people do eat them. If the flesh smells ammonia like, soak the fillets in salted milk for 24 hours. Also, Ken Jones knows quite a bit about the preparation of bat rays. Give 'Em Hell, Nate D

Posted by moe

Thanx for the reply Nate... are the smaller rays better eating than the bigger ones....maybe they would have less pollution in them?

Posted by Ken Jones

One and The Same. Probably 90% or more of the anglers around San Francisco Bay call bat rays sting rays and yes, they do indeed have a stinger/spine by their tail.
Rarely if ever would you catch a round stingray, diamond stingray or butterfly ray this far north. And manta rays are creatures more common to Baja waters — indeed they're even very rare to southern California.
As for their edibility, they're good. They are a little bit of a pain to clean; you need a strong and sharp knife. However, the bone-free meat has an interesting taste and texture.
Although I used to always use a pier gaff (at least on the higher piers), a net is better. A net allows you to release unharmed the smaller fish—and the larger fish if so inclined. A ray brought up from the depths by way of a pier gaff is probably not going to survive. To be honest though, many anglers, including myself, today release most of the bat rays we catch. They're great fun to catch and deserve to fight another day. But that is a personal decision.

Struck out twice vs. huge rays; guys I need some help. I have struck out two nights in a row on the ol' mighty bay ray.... One took me out like 150 yards, then came back straight at me, by the time I caught up with him he was already under the pier, getting himself ready to wrap me around one of the posts... and as you figured, indeed he wrapped me around not once but several times, and the 30 pound shock leader I had broke!!... You gotta love it!! This guy must have been huge...I felt as if my 12’ surf rod was going to snap in half!!
The other one, I didn't even get the chance to adjust my drag.... he took the bait.... then just took off.... I set the hook but he just kept running, till me line snapped again.... twice in the same night...Don't know what the second one was.... maybe a shark or a ray? I need some help on the issue.... any suggestions for next time I go out? thanx

1) Use a conventional reel instead of a spinning reel. A high speed reel will help your first problem although they do that sometimes and there's nothing you can do about - part of fishing from a pier. I've never caught a yellowtail from a pier and the pilings are the reason why.
2) Use a 7 or 8 ft. rod rated for 20 - 40 lb. test (or somewhere in bewtween) designed for use with a conventional reel. I've seen so many people loose rays because they simple can't control them with those long surf rods.
It's much easier to fight large fish on conventional gear. You use your bicep instead of your wrist and forearm. The drags are usually better and even if they're not you can always loosen it a bit and control it with your thumb (be careful not to burn your skin off). You can set the alarm instead of loosening the drag (which will eliminate the second problem you had). I don't mean to toot my own horn but I can cast further with my 7 ft. Musky rod and Daiwa SL30SH with 20 lb. test further than anyone I've ever seen on Goleta pier with one of the ridiculously long surf rods and spinning reels. Anyone can do it with a little practice.
I have caught countless large (up to 56 inch wingspan) rays on medium casting rods and I've never used anything more than 30 lb. test. These days I stick to 15 and 20 (25 if a friend who doesn't fish much is with me - on his/her rod).
With a decent rod and reel and a few rays under your belt you can easily handle most of them on lighter tackle - not to mention it's much more fun and challenging.

Subject: STING RAYS

I heard that when you catch a ray, you are supposed to cut the stinger off. If this is true, how are you supposed to do it? So I cut the whole tail off or just some part of it? Thanks.

Posted by Iso Lunkers

No... No cutting anything off. First of all, you need to make sure it is a “sting ray” and not something that has no stinger in the first place. Then, you want to bring a towel to grab its tail so you do not get slapped with it, plus it is one of the only ways to hold them when throwing them back in and unhooking them. I have seen people cut the tail off and that is just plain cruel. I hope this helps.

Posted by mobilesuit

Thanks for the feedback. So basically you don’t do anything to it right? k. Oh and um, when you do hold the ray, where do you hold the tail with the towel? And how thick should the towel be? It just seems like I can still get stung, even with a towel. Well, thanks again for the feedback. Good fishing.

Posted by Black Marlin

Mobile-I have landed well over 500 bat rays and skates since I started fishing for them at 12 years old. I used to cut off the stinger from rays when I was young if it was really big, as the stingers reflected the overall size of the ray. I kept them in my tackle box and they served as a sort of status symbol in the pecking order that existed in the small culture of ray fishermen in my town (Sausalito, CA). Now, I still fish for and catch many rays each year but as a wiser, more cultured man I've dropped the stinger cutting and replaced it with a cheap camera and tape measure. I think if you are going to catch and release any fish, it must be returned to the water as it came out, minus the hook in it's mouth. No exceptions. Best of luck. Give 'Em Hell,, Black Marlin

Posted by Leapin Bass

Although it is not necessary, cutting off the stinger is okay if you really feel you need to because it will grow back relatively quickly (they do this in aquarium touch tanks like the one at the Monterey Bay Aquarium). Definitely do not cut off it's tail because then it's stinger (which is it's only method of defense) can not grow back. It also helps to know where the stinger is - at the base of the tail. Some people think it's on the tip of the tail.
One time at Goleta I saw some guy who was fishing with a bunch of rods, keeping illegal-sized bocaccio and using them for bait. He caught a small bat ray, cut the tail off thinking he was safe and then got nailed by it's stinger as he threw it back (oh yeah I forgot to mention that the jerk gaffed it to bring it in - then released it!). Anyway, him and his buddy left immediately (I assume to a doctor or hospital) which gave me his spot on the end of the pier.
I've seen a few people cut only the tails off and not the stingers but this was the first guy I saw get nailed. I felt it was justice for all the other crap he was doing illegally.

Posted by Ken Jones

If you are in a group it is often possible to have one person hold the tail (with a towel) while you remove the hook; then let the stingray go. However, I am often alone and at times it may be hard to remove the hook in a safe manner, especially if the fish is hooked deep. What I do then is to grasp the tail with needlenose pliers and cut off the stinger (spine). The ray is then safe to handle and the stinger will grow back in approximately 4 weeks time. DO NOT cut off the entire tail.

Posted by readership

Is there a trick to bringing up big fish (such as stingrays) when you are fishing alone? I was at Pacifica Pier the other night and landed a fatty smooth hound shark. Luckily there were some crabbers to help me out, whom I gave the catch too. otherwise, winds blowing, flashlights barely shining, eyes straining, whew...fish on!

Posted by Leapin Bass

Walk it to the beach if you have a fishing license. Otherwise - good luck!

Posted by mobilesuit

What are the chances of getting stung? I was wondering what were the chances of getting stung by a stingray you just caught. (When you’re shore fishing that is). I don’t know if you’re supposed to but I always go into the water about knee or thigh deep to cast, because I have a short rod and am also not the best caster. Thanks for the help. gl fishing

Posted by Leapin Bass

According to the guys in Grand Cayman stingrays do not sting when they are swimming around - only when they are sitting on the bottom. When you wade in the ocean don't take steps - instead shuffle your feet which will scare the stingray and cause it to move.

Posted by mobilesuit

Stingray on its back. If a stingray is on its back, will it not be able to sting you? Heheh just a thought from an earlier question. Thanks for your time. gl fishin

Posted by Red Fish

A Serious Question, Right? A good one too. Many anglers that catch stingrays (O.K., proper name Bat Ray's Ken!) for the first time don't have a clue how to properly un-hook them or of the potential danger of being stung. The first time I caught one, about age 14, I was clueless. Two guys that called themselves helping me, cut the poor ray's tail off, then I threw him back. They told me, “oh, he will grow another one just like a lizard.” I don't know that to be a fact, but it is senseless to cut off a ray's tail and I have never done it on the dozens of ray's I have released over the years. O.K., yeah, I believe turning a ray over GENTLY on his back is the best way of un-hooking it. This way the ray's stinger in face down. If you look at a ray's tail, there is only one small stinger located at the front of tail anyway very similar to a catfish's spines on its head.
So, after that long explanation, the answer to your question is No. A stingray will not be able to sting you on its back (it would be very difficult to do so.) Anyway, if it's on its back the hook is in its mouth, right? O.K. you shouldn't be standing near its butt when you’re taking out the hook! Hold the ray's tail down with your foot if you’re really worried about being stung.
Oh-lastly, ever so important. When you go to release this puppy, hold it near the head (mouth) with the tail away from you when you go to throw him back!!!! Hope this helps.
I am curious to know if anyone on this board has ever been stung by a ray? Please share your story with us.

Posted by ikiller

I was stung once. My stinging story: I was fishing on either McNears Pier or Paradise Pier, I can't quite remember. Well I caught a rather small ray with probably a foot and a half wingspan. I wasn't very familiar with the handling techniques since I had just started saltwater fishing. I was hauling it up by the fishing line, and I guess I was too close to the railing. Somehow it whipped its rear end through the railing and stung me in the side of my left calf. I did not notice that I was stung for a few minutes while I was dealing with the fish. The stinger (or whatever you would call it) went through my jeans and at least a half-inch into my skin. It wasn't that painful of a wound. It was kind of a mild cold shooting pain that persisted for a few days.
When I catch a ray on the beach here is my technique: Drag him up out of the water onto the beach (not too far from the waters edge). Grab it by the front edge of a wing and flip it over. Remove the hook, stand on the tail if necessary. After the hook has been removed, put a hand under the leading edge of each wing and flip the whole thing over head over tail. If you have done this technique correctly (and you were close enough to the water) you will have turned the ray over and flung him back into the surf.

I have been stung by a ray once. I was out at Baker's Beach a few years back fishing for some stripers, and my uncle landed a small ray, maybe 2 feet in diameter. We flipped it on it's back, and started to take out the hook, I was wearing some Nike sneakers with flat bottom soles. I pressed the tail down into the sand to stop it from whipping back and forth as I held on to the line so my uncle could take out the hook.
Some how, the ray managed to free its tail and stab my ankle with it's dagger. It went through my shoe, my sock, through my skin, and it did hit the bone in my ankle. There I felt a mild electric current flow through my leg as it throbbed while the blood oozed out. It hurt like a b!tch. I screamed and yelled as I tried to hold back from the pain. Basically, it sucked, the scar hasn't gone away, and the wound looks the same as if it were the day when it happened. tony

Posted by Black Marlin

Mobile-One thing people are omitting when talking about getting stung by rays is the ray's tail itself. On a mature ray (40# and up) the tail is like a bullwhip, and the ray can use it as such. I have been thrashed by a ray's tail a couple of times and it drew blood and left welts both times. Either use a glove and hold the tail or cover it with a towel and hold it down with your foot. I have landed and released well over 500 rays in my years and the best way to remove a hook is with the ray on it's back holding down the tail with your foot. Happy fishing!!!! Black Marlin

Posted by papa

I use this technique of using a towel on the tail also. When I throw the ray back I usually pick it up with my thumb and index finger in what I think are the gills on top of the head. Is this a good way to handle a ray. Its tail can not reach up to my arm and I always hold it away from my body. Just curious.

Subject: bat ray stingers?

Hey. do bat rays actually sting with their “stinger?” I know what they look like and I have a few small ones. Kinda like a little knife in a sheathe at the base of the tail. Really sharp and barbed. Could cause some serious lacerations. But does a live stingray posses venom or a painful fluid besides that? Not that I plan on finding out the hard way anytime soon. Anyone know anything about this?

Posted by Leapin Bass

Do not find out! They do sting with their stinger and it SUCKS! I don't think what stung me was a bat ray. Since it was so shallow I believe it was a round stringray but I'm not sure since I didn't see it. In either case it was probably the worse pain I've ever felt (and I've been through some pain!). It was two weeks ago and the area around the puncture is still slightly swollen and sore.

Subject: Pier nets?

Man I need a net for bat rays. I looked all over the place. Fact is they don’t make those landing nets anymore. At least that's what I’ve been told by the tackle shops in SD. I mean, if you just want something to bring up a bass or a barely legal halie with then a crab net should do. But for bat rays I had to go and buy a nylon tailgate net for a truck. I attached some rods to the ends to keep them open and tied about 25ft of line to each end. I haven’t gotten the opportunity to use it yet but I think it will do fine. But just for the big fish. I’ll probably post more about it if I ever get to use it and it works. But hey, if you’re looking for something of the same nature and you find one, let me know!

Posted by PierHead

Good idea! And portable too - you just roll it up. I got several questions:
1. How big a ray can be pulled up by net? Are their special techniques when hauling up a load like some of Stan's beasts?
2. How did you tie off the 2 lines to the net - I could see the net revolving (horizontally) and tipping the fish out. Did you string it up like a hammock?
3. Will the rules inhibit the cutting off of the ray's stinger? How does everyone feel about that?
Tight Lines! PierHead

Posted by pescador5312

1. I don’t know how big a ray can be hauled up since I haven't gotten the opportunity to use it yet. But it is very portable and saves a lot of space.
2. Yes it is strung up like a hammock. My plan (for when I do hook up) is to have two people ready with each rope (whereas I can be one of them). I just guide the monster into the net kinda like a trout cradle net. Then bring both of the ropes together to haul the fish up. It should be in the position where the wings will just be bent upward when the net is closed so the tail doesn’t get caught in the holes. It just hangs off the side.
3. I’m not going to make it to the derby. Wish I could so I can’t answer that. But I myself don’t like to take the stinger off regardless of whether or not I feel I might be in danger by leaving it on.

Posted by Songslinger

I Leave The Stingers On. I don't see the point of returning a fish to the water without its natural defense system intact. But others like to carve out stingers for their collection and the stingers will grow back. So I guess it's personal choice. If the issue is safe handling, then you really don't need to remove the stingers so much as keep alert. Pretty obvious, in my opinion, where the sharp end is; you just have to avoid it. A good landing net is preferable. A crab ring is best for piers. The less damage you do to these creatures, the better. I tend to cut the hook with a wire cutter if it means the difference between the creature's comfort and my tackle. Also, and I'm not signaling anyone out here, I don't care about taking pictures and rarely pull my fish onto the bank.

Leave the stinger

Posted by Sinker

I will hold its tail while you remove the hook. The problem I have is when lifting the dog gone beasts up over the railing is when it gets a little scary. I have been hit twice that way but never while removing hooks. It does hurt like hell. I am allergic to bees and have to carry an Epi Kit with me but the Bat Ray sting has never caused me to go into shock. These new Kits are nice they auto-inject rather than the ole syringe "Get Bent" "Sinker"

Subject: Cutting off a Bay Ray's Stinger?

The other night I caught a Bat Ray that no longer had its stinger. From the looks of the wound/scar, it looked like somebody had cut the stinger off with a blade then threw the Ray back in the water. I guess the question to ask is why somebody would decide to catch the ray, cut off its stinger, then throw it back? Does the stinger have some sort of use for humans of which I am not aware, or was this just a pointless act of cruelty?

Posted by Songslinger

Some people like to keep stingers as trophies. I'm told the rays grow them back eventually. Even so, and this is my personal taste, I would prefer not to release anything shorn of its natural defenses.

Posted by Mike. C

Agree with Slinger on sending the ray back without its means of defense. That thing evolved to be there for a reason and we shouldn't screw with it. But as far as a random act of cruelty, I wouldn't go so far to say. The folks at the aquarium say that it causes no pain to the rays when they cut the stinger and they do grow back.

Posted by neptune1234

I always keep the stingers. Have a pretty good collection going too. Except I don’t cut them off. If you grab it at the base with a pair of needlenose pliers and lean it backwards they pop right off. NO sweat. Only a couple second operation. NO real harm to the ray. They’re mainly for use when they are babies anyway. I count them as trophies and put them on my weird fish stuff shelf. Always a nice addition. I suppose you could make earrings out of them.

Posted by RaySniper

Interesting...thanks for the info. I guess that it's just something that I personally wouldn't want to do...I guess that I am just too much of a softy. I suppose that there isn't much of a problem as long as taking off the stinger isn't causing the Rays any excessive harm...

Posted by baitfish

It is supposed to be like clipping a fingernail, they are designed to break off, but it does leave the ray defenseless. Adam

Posted by tomaurand

If it bleeds, infection can set and kill the ray! Really no reason to cut the stinger. Has anybody on this board ever been stung by a ray???? Like being stuck by a catfish, it was probably the not the rays (or catfishes) fault.

Posted by baitfish

I have never cut them before, has anyone had them bleed from cutting them? However the size of the are of possible infection would be about the same size as the hole left by the hook. The material of the stinger is made of Keratin, the same material as your fingernail. If you were to clip it, I don't see how it would bleed, but the popping method that neptune describes is different. You don't really need to cut them off, if the ray is flipped onto it's back, it presents little danger. Even then, keep your wits about you and safely return the ray to the water. Adam

Posted by neptune1234

The way I do it only takes a sec. Doesn’t leave any wounds. Just pops right off. Grab it near the base and bend it backwards. It’s almost surgical the way I do it. No harm done. I have yet to recatch an already de-stingered ray but I’M sure I will. The Monterey Bay Aquarium told me they grow back.

Yep... Last year while surf fishing. First - it is NOTHING like being stung by a catfish. I have lived through some pretty painful stuff (like my top lip being ripped in half-motorcycle accident) and I must say that the ray sting is at the top of the PAIN list. That freakin' hurt more than I thought anything could hurt. I was doing Lamaz breathing on the way to the hospital. I don't recommend it unless you like intense pain.
As for cutting the stingers off I've done it a few times when I was younger. There's really no need to though. It does leave the ray defenseless until it grows back (if you cut it off correctly). The sad thing is that I've seen people cut the entire tail off - that sucks!

Couldn't be like getting stung by a catfish I got stuck by a catfish when cleaning one as a kid and got part of the (stinger) lodged under the skin in my right index finger. It was similar to getting a splinter. Now I have never gotten stung by a bat ray but from what others have described that have been stung it sounds far worse than any catfish cut.

Posted by sharkshooter

Can you only get “stung” if the ray jabs you with the sharp end of the stinger, or is the whole thing dangerous? I've never gotten close enough to the business end to find out personally, nor do I care to. I always just flip them on their backs, pop the hook out, and scoot them back into the water to fight another day. but since some of you have already been stung, I may as well learn from it.

Posted by Ken Jones

In the past...I have recommended cutting off the stingers (not the tail) if anglers were concerned about handling the rays (for fear of getting stuck). I would much rather have the stinger cut off and see anglers handle the ray in a gentle manner than having it knocked around. However, I believe experienced anglers should be able to handle the rays safely without needing to cut the stinger off. As for harm to the fish, I have been told by several people who should know that there is no harm to the rays. The stingers are routinely cut off of the bat rays at the petting ponds at several aquariums. They grow back in about a month and are then cut off again. Sort of like cutting your hair. That way these creatures can be petted by our youngsters with little concern as to danger. The petting ponds are great, especially at MBA

Monterey Bay Aquarium. I think that visiting an aquarium should be a requirement for all novice saltwater anglers along with study regs prior to a license issue. I think it would avoid a great deal of the nonsense killing of sharks and rays by the uninformed.

The petting ponds are great, especially at MBA. So true. And a visit to the kelp forest exhibit is worth the price of admission.

That's some awesome engineering. That tidal tank with the kelp forest rises and falls due to a pump that resembles an oil well pump. Very cool stuff at Monterey. Maybe we should do a PFIC outing there.

They can release the stinger during a fight (don't even know if they grow back), but I can see some a*@hole doing that to render him defenseless to all of the other predators. Too bad for the bat, he's probably not gonna live much longer. It's lucky not to die from being cut up. People will often do that to crabs, but isn't that more cruel, than just refusing to release the animal back into the water? Eat the mother up if you don't want to run into it again! Survival of the fittest right?... not him now.. what a pity. Cut dudes hands off at the wrist and watch him get into a brawl.... not doin' too good I bet....same idea! Sorry just rambling, I hate to hear of people being cruel to animals because of boredom!.... that's why they call it fishin' not catchin'.... good ol' fishnchips!

Posted by gyozadude

Another source of damage... is getting cut up during the fight through entanglement. I used to fish braid for bat rays up through mid summer this year. But I started noticing the bright red lines where the braid had tangled with the ray and damaged the outside skin. In fact, some cuts were quite deep, and that really puts the ray at risk of infection or parasites. So I've switched back to 25-lb mono and thicker. It's less likely to cut than the much thinner braid. While it's stretches more and is quite thick, I think it's still beneficial to stick with mono in this case. Of course, mono is also cheaper.

Good to know, didn't think of that, especially dealing with bats! Thanks for the tip!

Is it true that you can put vinegar or if it really hurts and you can’t wait that you can pee on a bat ray sting or is that jelly fish? I don't want to pee on my self for the wrong kind of sting. Batman

Posted by pEsCaDoR619

Any kind of sting... you want to pour hot water (hotter the better) on it. This will break up the toxins and ease the pain. This is why they say to pee on it because fresh urine is very warm (no I’ve never been peed on). Breaking down the toxins will also lessen the chances of any delayed effects of it.

And that works! I know first hand-I got whacked by a stingray just a month or two ago, followed your instructions and the pain was gone in about an hour...

Posted by Anotherbite

On the Gulf Coast, the treatment I have know my entire life for jellyfish stings is rubbing dry meat tenderizer on the affected area. It always worked pretty well when I tried it. Has anyone else heard of this method, and if so, would it work on the sting of a ray?

Posted by baitfish

From what I have read the poison in stingrays is protein based, so the hot water actually cooks the poison, and neutralizes it. As for urine, I was under the impression that it was the ammonia in Urine that made it effective, anybody have anything on this? Adam

Subject: Best way to pick up a Bat Ray or.....

A Shovelnose Skate? I've seen guys pick them by sticking their fingers into their eyes but this just doesn't seem humane to me. Do they have teeth or would you recommend sticking your fingers into its mouth to hoist them up to get them over the railing? Any help would be a great education for me... Thanks in advance!! Mike RaidersFan1

Posted by pescare

Here's a past tutorial from Gdude. — Hoisting rays by the mouth

Posted by gyozadude on March 4, 2003

I've never been bitten while hoisting a bat ray by its mouth. And while I've had a few rays try to chomp down on my hand, they don't have teeth and it has never hurt. I only theorize that with all four fingers in their mouth, they really can't chomp down effectively, and once you've got them in the air with all their body weight hanging, they really can't do jack squat. So I'm just wondering if I've just been lucky, or if lifting by the mouth really is the proper hold. I have read that they can crush mussels, clams, and other mollusks so use the hand hold at your own risk.
I've seen people lift rays using a net, or by two hands, one in each nostril. But both ways can cause lacerations, especially on the big rays. Plus, it's messy. I don't know if you've ever gotten bat ray snot on your hands. The stuff is really viscous and it stinks. Not that I really mind while fishing, but if you've gotta go home and hug your babies, this ain't exactly stuff the spouse would approve of getting all over the kids. I've wiped my hands off on dry rags and then put them through the wash twice with hot water and extra detergent and still, the slime isn't completely dissolved. So I really like the mouth hold because it’s a lot cleaner.
Technique is pretty easy. With palm facing up, just reach down under and slip your hand into the mouth and curl your fingers up. You should feel the tips of your fingers curl in and stop against the roof of the mouth. Then hoist quickly, and you've got it.

Posted by newgen

Wow what a picture! I think that I will use that hold on them, it seems more natural, and less harmful to their bodies than any other hold.

Posted by prometheus

By the mouth is the only effective way to pick up big rays with one hand since their nostrils are too far apart. Watch out for your hook though!

Posted by pEsCaDoR619

I wouldn’t try it on a big shovelnose. I did that with a 4-footer once and got the chomping of a lifetime. No teeth, just sandpaper-like cartilage for lips. But that sucker had some power in them jaws. I hurt for a good couple hours.

Posted by gyozadude

Spend four years washing dishes. LOL! One way to toughen up the hands is to wash dishes. I did that for four years during high school and early college and grew some thick skin! LOL! Seriously, if you're afraid of the chomp, you can get some leather gardening gloves from Home Depot for a buck and that really protects the fingers. The key trick is assertiveness. You don't want to second guess the ray and wonder if he's gonna bite you. You just gotta stick your hand in there and grab it firm and hoist. If you dally too long, the ray might get the idea that it's got “finger food” in its mouth and chomp down or thrash. I don't think the chomp is all that heavy. The ray has mostly smooth plates inside its mouth and a couple of rows of ridges for teeth. If it chomps down, the ridges really can't cut you, but if the ray flaps around and you loosen your grip, that's where the ridges might slip and pinch you in the knuckles. So the key is to assert yourself, be quick, and be firm. Once hoisted, it's like a bass with a hyper-extended lower jaw - pretty much paralyzed and cooperative

Posted by sharkshooter

Yeah - I'm familiar with the slime. Part of the reason I’m thinking about picking them up by the mouth, besides not wanting to damage them. pescador's post makes me think twice about it, though...

Posted by prometheus

He's just warning you not to try it with any shovelnose sharks, or skates for that matter. They both have teeth.

Posted by sharkshooter

Hmmm... I thought he was saying it was the power of the bite, and not the sandpaper lips that hurt. I guess I'll try it with a glove first, and check for bite marks. Or I'll just have raysniper do it first. He'll do anything this board tells him to do.

Posted by lucy

Based on pics I've seen of the construction of a bat ray's mouth, I believe you're actually picking them up by what would, on a human, be the upper lip. The “plates” they use to crush oyster and other shells are actually farther inside the mouth, and unless you stick your fingers in there, you're in no danger of being hurt because they can't “chomp” with their lips.
I could be wrong about this, so don't anybody rely on this—and if you do, don't blame me if you lose some fingers.

Posted by andthelinegoeszziipp

Watch the stinger on the real small rays while gripping them by the mouths. They can actually curl their lower bodies and sting like a scorpions tail.

Subject: Seal Beach and stingrays —

“A quarter of all stingray-related injuries reported in the United States occur at little tiny Seal Beach,” says Lowe. “For locals who have lived here for a long time, it's commonly called Ray Bay.”
Forget Sharks, Watch Out for Stingrays, Jellies
July 23, 2002
Release from:
LONG BEACH, California, July 23, 2002 (ENS)
The greatest threats to California beachgoers in these warm months are jellyfish and stingrays. Sharks are a distant third, says Dr. Christopher Lowe, assistant professor of biological sciences at California State University, Long Beach.
A marine biologist, Lowe specializes in elasmobranchs - sharks, skates and rays - as well as game fishes. He says these sea creatures often move closer to shore during warmer months.
Jellyfish pose particular problems because they can be hard to see. “They get stirred up in the waves and the person gets stung and never sees the jellyfish,” says Lowe. “Generally, its sting is characterized by a light, tingly sensation that gradually builds into a burning sensation that tends to be localized where the tentacles make contact with the person's skin.”
Jellies “can have tentacles that can be very, very long - 30 to 40 feet when they're extended - so a person can be swimming along, get stung by a tentacle and never actually see the jellyfish,” explained Lowe.
As for treatment, “Often when people get stung, they have a tendency to rub their skin, and quite often when they do that, they just smear the tentacle over more of their skin surface. If you see the jellyfish, the best thing to do is to try to gently grab the tentacle - ideally with something other than fingers - lift it off and flick it away. People recommend trying to use a credit card or piece of cardboard to scrape it off without smearing it over the skin,” Lowe said.
Because the toxin is topical, vinegar is a good treatment, Lowe recommends. “You can use ammonia as well as Adolph's Meat Tenderizer. These will neutralize the toxin and take away the burn,” he says.
Getting stung by a ray is a more serious matter, especially if encountering a congregation of them. During the summer, stingrays move inshore and are most commonly found in estuaries, bays and along calm sand beaches, Lowe explains. “So the most likely places people encounter them would be if they were swimming at a bay beach or along a calm, sandy, muddy shoreline. They can aggregate in very, very large densities.”
When stepped on, a stingray whips up its long, barb-tipped tail.
“A quarter of all stingray-related injuries reported in the United States occur at little tiny Seal Beach,” says Lowe. “For locals who have lived here for a long time, it's commonly called Ray Bay.”
Lowe researches the reasons for the high stingray population at Seal Beach. It may result from the breakwater off the Long Beach coast, which reduces shoreline wave action from around Seal Beach to San Pedro.
The San Gabriel River has several power plants that dump warm water effluent into that river, and that warms the water at Seal Beach, making it attractive for these rays, Lowe says.
Development of many of our bays and estuaries into marinas has reduced the natural habitat for the four types of stingrays found along California's nearshore - diamond ray, round ray, butterfly ray and bat ray.
“So what we've done at Seal Beach,” Lowe says, “is, that through urban development, we've created a super habitat for some of these stingrays, and unfortunately, it just happens to be the same super habitat that humans like to go surf and swim and play in.”
‘In summer, we believe the rays are coming in to mate, and later in the summer, females are probably giving birth to their pups; rays give birth to live young,” said Lowe.
“The females might be staying in the warm water to speed up their gestation rate so their pups will develop faster. So the places where people are most likely to encounter them are when they're walking around a shallow bay area through water that might only be a meter deep.”
The best way to avoid getting stung is to do what Lowe calls the “stingray shuffle” sliding one's feet through the sand and under a ray. This will generally cause it to swim away without lashing its tail.
Stingrays are found right in the surf, and they also congregate just beyond the breakers. “A lot depends on the surf,” said Lowe. At places with milder waves, “we found stingrays right into the surf zone. By having that flat body, they kind of stick to the bottom and don't get tumbled around. But that's right in the place where people can't see very well and as they're walking through, that's probably when they'll accidentally step on one. But once you're just beyond that zone is where we tend to find the greatest densities.”
Unlike the gradual sting of a jellyfish, “As soon as somebody gets stung, they're going to know it, because it's a barb that actually penetrates the skin and creates a wound," said Lowe.
“Something has actually poked into your skin and there is mucus that covers the barb. Embedded in that mucus covering are toxin cells, so as the barb punctures the skin, it causes those cells to rupture and the toxin leaches into the individual's skin,” is how he explained the pain.
“The first thing the individual should do when they're stung is to do their shuffle back out of the water and try not to get stung again,” Lowe advises, “because quite often people hobble and when they do that, they take the chance of being stung again. You've got to think of it like going through a minefield. These animals are very social and tend to congregate. People ought to try to go back out the way they came in.”
“The general treatment is, first of all, make sure the wound is clean,” he said. “They should make sure the barb is no longer in there. The little barbs allow it to get wedged in, but when it pulls out, it pulls out a little bit of flesh and that helps rupture those toxin cells.”
In rare case, if the puncture is deep, the spine will actually pull out of the ray and get embedded in the individual's skin. Then a medical doctor should remove it.
“In most cases it's just maybe a quarter of an inch or smaller that penetrates the skin - just a quick poke is all it takes. It's extremely painful. It's not uncommon to see the toughest surfer dude weeping,” Lowe observed.
“As long as it's clean and there are no bits of spine left in there, the best treatment is hot water - as hot as they can stand it. That helps denature the toxin. The general treatment should last an hour or more.”
For any type of beach injury, it's best to seek medical attention from lifeguards who have the necessary training and equipment. The greatest concern is for individuals with severe allergies to stings. “Those people can go into anaphylactic shock and that's why for some people, getting treatment right away is important,” said Lowe.
He advises such people to carry their anti-sting epinephrine medication. “It's something people don't think of taking to the beach.”
Lowe and his team of student researchers have been involved in discovering ways to help reduce stingray injuries. “In Seal Beach, the city has been looking at ways of reducing injuries to the public, and they've tried everything from eradication to translocation - trying to move as many as they could.”
Since none of these efforts were successful, or were considered to be ecologically reasonable, Lowe proposed a stingray barb-clipping program. “The barb is similar to a fingernail; it's basically a modified scale,” Lowe said. “It doesn't have any nerves leading to it, so you can clip off the pointy end.”
But after two years of clipping the barbs of about 2,000 stingrays, Lowe and his student team found that these rays replace their spines every late summer to early fall. A new spine grows in, the original spine falls off, so at no point are these rays really without a spine.
Lowe has concluded that the barb-clipping technique will not work at the scale that they were doing it. He now believes that “the answer is better education.”

That's where I got my sting...Seal Beach, except I caught the stingray off the pier and got stung trying to handle it. I'm sure the stings would be much worse if you were in the water and actually stepped on one.
There's a funny story here, too. As I was taking pictures of the wound, a couple was walking on the pier and came over to see what kind of weirdo was taking pictures of his own bloody hand. I told them that I just got stung by a stingray, and apparently they had a friend who'd also been stung recently. The husband said, “You can put some steak sauce on it and it should feel better.” I wasn't sure if he was serious or not, so I kind of smiled and said, “ahhh.” Then the wife looked at him quizzically and quipped, “Not steak sauce...MEAT TENDERIZER!” We all had a good laugh after that.
FYI the wound was only about 1/4" wide, but it was a little bit deeper than 1/4" and was on the meaty side of my hand (pinky side). The stingray itself was no more than about 10” across.
The initial sting was obvious. Within 10 minutes it was annoying. After 30 mins it was hot, and the pain had spread through to my pinky. After an hour, half my hand - including the pinky and ring finger was extremely numb and the pain was pretty sharp. In two hours it was difficult to close those fingers. I'm probably stupid for doing this, but I never really took care of it and wanted to see what would happen with this sting.
During the next four weeks or so, the side of my hand was extremely hard and swollen, and sometime bluish. I would occasionally squeeze some fluid from the wound, but when I did this the swelling would increase over the next couple days. I was probably spreading around whatever toxin was still in my hand. It remained hard and distended and sometimes sensitive through about the 6th week, and then everything kind of went away. I still have a tiny scar to show for it.
Lesson: If you get stung, use meat tenderizer...NOT steak sauce!-Matty

Subject: Question about stingers...

Anyone who's been to the Monterey Bay Aquarium knows they have a bat ray petting tank. Last time I was there, I checked to see if their stingers were removed. They weren't. Does this kiddy petting pool prove the stingers aren't too dangerous? I've never seen some one get hurt by a ray's stinger while it was on its back on land.

Posted by wang

I was told they cut them off (or down). I volunteered at the Aquarium of the Pacific for about a year. I was told the stingers are cut every 2-3 months. The stingers on ray are like fingernails, they grow back. The only downfall is, if they loose their stinger, that they are defenseless until it grows back. The tails doesn't grow back if they are cut off.

Posted by eelmaster

The stingers WERE removed last time I was there.

I would imagine it to be like a scorpion sting, or perhaps I may be wrong, it might be much more painful! Don’t want to find out.

Posted by Clayman

Have you looked at the size of those stingers on bat rays? They're huge, and covered with slime. I've never been stung by a scorpion, but I'm sure a sting by a bat ray would REALLY hurt, and it would probably get all infected real fast. For sharp stingers, it's hard to beat the two spines on spiny dogfish. Now those things are big AND sharp!

Posted by stripesidechaser

BTW, that isn't slime on the stinger! That is actually a skin covered poison filled pod. The affects the nerve endings and causes intense pain (as if a 4" long, 1/4" wide barbed spear isn't painful enough). When they stab an object, some of that “pod” breaks off inside (unlike RH's buddy, most of the time the sting comes back out). I saw an extremely drunk guy get stung in the calve... That dude went sober!

Posted by q3fishboy

The Monterey Bay Aquarium does clip the stingers off of all the bat rays and stingrays that may be touched on display. As previously stated, the stingers are similar to our fingernails, and are actually made from the same protein. I have heard that the Monterey Bay Aquarium will catch bat rays, cut off the stinger, and put them in the touch tank. After the stingers begin to grow back, they will put them in a different tank where they cannot be touched. Finally, after the stinger is completely regrown, they will return the bat rays to the wild. I do not know if this cycle is true, because before the upgrade to the tank, I could actually recognize all of the rays in there individually. Though they have all changed since the upgrade, I don't know if that actually cycle them regularly. However, they do clip the stingers off.
If you go to the Sharks Mystery and Myth touch tank and look at the round sting rays, it is much more noticeable and you can see exactly where the stinger used to be, as there is a small depression in the tail. However, the spines on the horn shark are a different structure, and do not grow back, so the Monterey Bay Aquarium does not trim them. However, they do have horn sharks in the touch tank in Sharks Mystery and Myth. So, they attempted to take a nail file and file the spines so they were not as sharp, which kind of worked.
Sorry about the long post, but I have spent way too much time at the Monterey Bay Aquarium, and though I have no official affiliation with the place, I really love it.

I know a lot of people post BAT RAY pix here on the message board and hopefully most of them are returned to the water, much like one of my past 170# plus MAMMA BAT RAY that was returned unharmed to give birth.
What really irritates me is when ignorant people keep cutting off and mutilating the STINGERS and TAILS of these great fighters, just to throw them back into the sea to DIE later. I once hassled a jerk on NP PIER as to his cutting these STINGERS off only to put another one in his little glass “BRAGGING” collection jar.
TROPHY JAR, I think NOT!!
STUPIDITY JAR, YES!!
After we all got on his case and made him look like an idiot in front of all the people crowds he attracted I think he finally got the message he wasn't wanted there, and never has come back to my knowledge!!
Many BAT RAYS are left TOO LONG on the HOT CONCRETE PIER DECK to cook inside and or suffer organ damage from their excessive body weight on them, as they are a fish out of water once brought ashore, or taken out of their water element. In the water they are virtually weightless! I've seen many a dead BAT RAY under the piers while scuba diving to know!!
Eating them is one thing as a food source if they are big enough, as there is no size limit, bag limit, or species restrictions of any kind on them, and maybe there should be. A BABY KILLER is a bay killer by any means, all restrictions set aside. Hope my input sheds some different light on these often misunderstood yet magnificent fighters of the deep blue sea! Happy fishing, Frank

Stingrays do not “attack” aggressively, or even actively defend themselves, when threatened their primary reaction is to swim away. However, when they are attacked by predators or stepped on, the barbed stinger in their tail is mechanically whipped up, usually into the offending foot; it is also possible, although less likely, to be stung “accidentally” by brushing against the stinger.
Contact with the stinger causes local trauma (from the cut itself), pain and swelling from the venom, and possible infection from parts of the stinger left in the wound, as well as from seawater entering the wound. It is possible for ray stings to be fatal if they sever major arteries, are in the chest or pelvic region, or are improperly treated. Their stingers are normally ineffective against their main predator, sharks.
Treatment for stings includes hot water (as hot as the victim can stand), which helps ease pain and break down the venom, and antibiotics. Vinegar or urine may or may not be successful in easing pain; neither cleans the wound properly. Other possible pain remedies include meat tenderizer. Pain normally lasts up to 48 hours but is most severe in the first 30-60 minutes and may be accompanied by nausea, fatigue, headaches, chills, etc.

Myliobatis californicus (bat ray and bat sting ray)

Geographic Range

Bat rays are found in shallow waters and coral reefs from Oregon to the Sea of Cortez.

Biogeographic Regions: pacific ocean (native ).

Habitat

Bat rays are found living close to the shores of bays, sloughs, kelp beds and coral reefs. Bat rays prefer to live in areas with sandy or muddy bottoms for it allows easier access to food. They are most commonly found in depths reaching between 3m and 12m but have occasionally been spotted as deep as 46m. (Gray, Mulligan, and Hannah, 1997; Last and Stevens, 1994)

Aquatic Biomes: reef; coastal.

Physical Description
Mass

Bat rays are commonly distinguished from other rays because of their distinct, protruding head and large eyes (a close look). They have a flat body with a dorsal fin at the base of the tail. The tail is whiplike and can be as long or longer than the width of the body. It is armed with a barbed stinger that is venomous. Bat rays are named for their two long pectoral fins that are shaped like the wings of a bat. The skin is smooth, dark brown or black and has no markings. Bat rays have a white underbelly. The skeleton is made of cartilage, instead of bone. Bat rays are usually born measuring 11.4 inches and can grow to reach 5.9 feet. Females are typically larger than males and have been found weighing up to 200 pounds. (Details.) (Last and Stevens, 1994; Michael, 1993)

physical features: bilateral symmetry .

Reproduction

Bat rays reproduce on an annual cycle, usually copulating during the spring or summer of one year and then giving birth the following spring or summer. The male chooses his mate by following close behind her and assessing her reproductive condition by smelling her chemical signals. When the male has found a suitable mate, he continues to swim close behind and moves under so that his back is touching her stomach. He rotates a clasper up and to the side of the female. After inserting it into her cloaca, they swim together with synchronous beats of the pectoral fins. Many times, males will fight over a particular female. The female may end up having more than one male clinging onto her pectoral fins at one time and will wait for one of the males to finally flip her into the correct position. Bat rays reproduce in large mating aggregations with the females clustering in one area. Females may lie on top of one another, burying females that have already mated or those that are not sexually mature yet. This allows less confusion for the males to pick a suitable mate.

The gestation period is between 8-12 months and the number of live young born depends upon the size of the mother but can be up to 10 pups at a time. The female enters a bay area to deliver in an effort to protect from larger predators in the ocean and to allow access to a more stable food source. The young pups do not require any parental care and are born with stingers ready to protect from predators. Before bat rays are actually born, the stinger is pliable and has a sheath that is sloughed. It protects the mother from the dangerous stinger during delivery but is immediately lost at the time of delivery. Bat rays reach sexual maturity around the age of 5 years, usually when they measure from wing tip to wing tip 67-68 cm. (Last and Stevens, 1994; Michael, 1993)

Behavior

Bat Rays are usually solitary animals but have been seen swimming in groups of thousands. They also swim with other rays from the same family (eagle ray). Females stick together and usually live where large amounts of food are found. Bat Rays move around a lot, even during copulation, and are noted for their ability to "jump out of water" and skim along the surface for several seconds. This is often described as looking like "flying". (Gray, Mulligan, and Hannah, 1997; Last and Stevens, 1994)

Key behaviors: natatorial; motile .

Food Habits

Bat rays are carnivorous and feed on a variety of molluscs, crustaceans, and small fishes. They have adapted to eat whatever food is most abundant in the environment, which may include polychaete worms, abalone, oysters, snails, shrimp, crabs, and bony fish. Juveniles eat clams while adult bat rays are the only stage that eats echiuroid worms.

Bat rays use their snout to dig invertebrates from the sand, making the bat ray an important benthic predator. They also capture prey by lifting the body on the pectoral fin tip, flapping the pectoral tips quickly up and down, and then using the suction created by the flapping to pull sand out from under the body, exposing hidden prey. When bat rays feed on molluscs, they eat the entire animal, crush the shell inside of the mouth, spit out the hard shell pieces, and then eat the soft part of the mollusc body. Bat rays, depending on size, may burrow with their nose deeper into the sand or mud bottoms in an effort to eat larger prey. (Gray, Mulligan, and Hannah, 1997; Talent, 1982)


Economic Importance for Humans: Negative

Bat rays feed on oysters in large amounts and because of this, they are considered a great threat to oyster growers. As a result, oyster growers in the Humbodlt Bay area have trapped them for over 37 years. (Gray, Mulligan, and Hannah, 1997; Michael, 1993)

Economic Importance for Humans: Positive

Because bat rays are large predators that use their snouts to dig up food, they wind up creating extremely large pits up to 4m long and 20 cm deep. These large pits allow access to small organisms that may be the food of smaller fish. Small fish rely on this relationship with bat rays because a lot of them are unable to dig their own food out of the sand.

Other Comments

* Bat rays have been known to live up to 23 years.
* Predators of the bat ray are the California sea lion and the broadnose sevengill shark
* Bat ray fossils have been discovered in Pliocene deposits dating back 1 million years.
* The origin of the name "bat ray" was given by Gill in 1865 because of their pectoral fins which resemble bat wings.
* Bat rays have been successfully bred at Sea World.
