Rays

although mata rays have tails, they are NOT barbs, they are not poiseness nor electrical

Sting rays give birth to live young

It isn't. A stingray is a cartilaginous fish and thus a vertebrate.

Jawless fish are included in subphylum Vertebrata, but most jawless fish do not have whole vertebrae. Hagfish, for instance, do not have vertebrae at all, and lampreys have only reduced vertebrae. So, no, most jawless fish are not vertebrates.

I'm not sure about all species, but many can be, including the giant freshwater stingray in Thailand. South American stingrays are hunted by the natives as a food source.

I fried some and ate it yesterday. I was wonderful, little like shark.

I have never heard of people poaching manatees; mainly the problem is motor boats accidentally cutting them with their motors or people harassing them. If anyone were to poach them, I'd say it would be because they are endangered, and their skin would be very rare and probably valuable in the black market.

Due to the size of manta rays, their only predators are large sharks.

Yes, stingrays can pose a threat, and could possibly cause one to die. Apparently, they are "cousins" of the shark. It's well-known that a stingray was what caused the death of the "Crocodile Hunter" Steve Irwin. While sharks have very powerful bites, stingrays have a spiney "tail" and small mouths. How can they be so vicious? Well, the tail stiffens when a stingray feels threatened, and kind of like a serrated blade with a deadly mixture of venom, it can produce enough power to kill its predator. Typically, stingrays pose very little threat to humans unless stepped on. It would definitely be painful to get "stabbed" by the spine, yet ultimately the threat remains minimum for humans. Steve Irwin probably died when the stingray pierced his heart; a tragic way to end one's life, and very unfortunate that it happened like that.

Sea Lampreys (petromyzon marinus) also known as Great Sea Lamprey, Lake Lamprey, Lamprey Eel - is an invasive predator or parasite that feed on a wide range of salt and freshwater fish (herring, mackerel, salmon, and trout). It attached itself using its sucker type of mouth, using it rough tongue it creates a hole on the surface of the host, allowing it to suck the blood and body fluids. The saliva of the lamprey prevents the wound from clotting. The host fish is seriously wounded but often is the case it is killed immediately or will die from an infection from the wound.

Stingrays feel like wet rubber. They feel like they're slimy to touch but they actually don't have any slime on them.

These animals are predators, and they eat all types of invertebrates and also fish, that they catch near or upon the bottom of the ocean (or rivers, in the case of the few freshwater species).

If you look at the ventral side of a ray you'll see its mouth, which appears small and pretty harmless because they don't have sharp teeth like the sharks, but sets of rather flat plate-like teeth.

However, rays can protrude their mouth (i.e. extend it forward outside their body) markedly, and their jaws are quite strong. With those teeth they can crush the exoskeleton of molluscs and other "hard" animals, as well as softer worms and fish.

In addition, stingrays are not as benthonic (bottom-dwelling) as the skates (the ones without stings). They use their wing-like appendages to swim in the water column - some even jump off the water - and can hunt for their prey in all types of oceanic pelagic (=open water) environments.

Bear in mind that the largest of stingrays (the manta rays) are mostly planktophagous (they don't eat large prey, they filter small planktonic animals using special "rakes" situated in their gills).

basically,it depend on what species of the bats is.you can determine it by the morphollogy of the bats mouth,it's describe what they eat.just easy as A,B,C

The manta ray (Manta birostris) is the largest species of the rays. The largest known specimen was more than 7.6 metres (25 ft) across, with a weight of about 2,300 kilograms (5,100 lb). It ranges throughout tropical waters of the world, typically around coral reefs. They have the largest brain-to-body ratio of the sharks and rays.

Chondrichthyes or cartilaginous fishes are jawed fish with paired fins, paired nostrils, scales, two-chambered hearts, and skeletons made of cartilage rather than bone. They are divided into two subclasses: Elasmobranchii (sharks, rays and skates) and Holocephali (chimaera, sometimes called ghost sharks).

If you want to yes. It is much better fresh. Just make sure your bag is tightly sealed with no air inside. It will last for months in the freezer, but when you thaw it out it wont taste as good as sashimi. You need to pan sear it or grill it and make ahi fish tacos!(My favorite)

I have been fishing, preparing, cooking and serving stingray, skate and shark meat for more than 40 years; and I can tell you, definitively, that the majority of seafood restaurants serve cookie-cutter plugs of stingray, skate and shark as "sea scallops"...

Anyone who is well familiar with the texture of stingray, skate and shark can INSTANTLY identify the bogus scallops. True sea scallops and bay scallops DO NOT have striated (fibrous) muscle tissue, as do sharks, stingrays and skates. A bogus scallop will look like a cross-section of striated muscle tissue. A TRUE scallop has a smooth, uniform texture.

There are many chefs out there who will SWEAR that it's illegal to market shark and stingray as "real" scallops, but that is simply not true. It's my conjecture that such chefs are covering their own practice of substituting shark and stingray for other delicacies on their menus.

If there are such laws, then seafood restaurants all over the USA are violating those laws with impunity, no doubt because such laws are not stringently enforced.

The argument that sea scallops and bay scallops are more plentiful and are cheaper than stingray, skate and shark meat is also preposterous. Bay scallop populations in U.S. waters are on the decline for various reasons, and many of their marine habitats have been declared endangered, under federal protection. Being on the endangered list DOES NOT precipitate lower scallop prices.

Small, whitemeat sharks and stingrays, on the other hand, are abundant in U.S. coastal waters in the EXTREME, and very few sharks, skates and stingrays are on the endangered species list. These boneless, whitemeat fish are REGULARLY used as substitutes for a whole range of marine delicacies, and most unobservant consumers can't tell the difference.

Hammerhead Sharks are carnivorous predators. Their diet includes fish, squid, Octopus, Crustaceans and Sting Rays. Sting Rays are one of the hammerheads favorite prey species. Large Hammerhead species esp. the "Great Hammerhead" is known to feed on other hammerhead species as well. Hammerheads are also cannibalistic, they eat their own young ones.

Because it is part of the ray family, it has a nasty barb on its tail that burys into the sea bed. If it attacks it stricks with its barb which would give a sting.

The wing tips of some rays are delicious. The ones I know to be tasty Atlantic species (I've only been offerred those), are benthic (they stay near the bottom) and predators (as opposed to filter feeders). These are taxonomically close to shark, and they taste like it. REmember that they're called "stingray" for a reason, and avoid the tail. Also note that some rays, like California's Torpedo Ray, use a mechanism that may be similar to the Electric Eel, in that they produce a SERIOUS electrical charge, that can easily knock you down. Also, in the tropics in particular, these are "tourist fish". Lots of people visit their basking grounds and, as the animals are no longer aggressive or fearful, and are fed by tourists, the locals (who make money from this phenomenon) and the tourists (whi think this fish is friendly) present a real danger if you decide to fish these up. My advice? Check with the locals first to see if you can eat them. Take only enough for dinner and then stop -- no overfishing. Don't make a show of it.

stingrays do not bite they have a stinger in the tale

In the ocean ecosystem, bull sharks are at the top of the food chain web. It is a predator that preys on fish, turtles, dolphins, and other sharks. Because they have few to no natural predators, bull sharks are considered apex predators.

- B vitamins

- Ask your pharmacist for over the counter preparations that can help.

- "Hair of the Dog" - not recommended (a small drink of alcohol).
