Stingray



Stingray 
Stingray  is a mollusk fish . It is very dangerous . It has a poisonous barb , it can kill a human beings. It eats fishes and have enemy like orcas.


Behavior

Stingrays feed primarily on molluscscrustaceans, and occasionally on small fish. Some stingrays' mouths contain two powerful, shell-crushing plates, while other species only have sucking mouthparts. Stingrays settle on the bottom while feeding, often leaving only their eyes and tail visible.Coral reefs are favorite feeding grounds and are usually shared with sharks during high tide.


Stingray injuries

Stingrays do not aggressively attack humans, though stings do normally occur if a ray is accidentally stepped on. To avoid stepping on a stingray in shallow water, the water should be waded through with a shuffle.Alternatively, before wading, stones can be thrown into the water to scare stingrays away.


Ecotourism

Dasyatids are not normally visible to swimmers, but divers and snorkelers may find them in shallow, sandy waters, more so when the water is warm. In the Cayman Islands several dive sites called Stingray City, Grand Cayman, allow divers and snorkelers to swim with large southern stingrays (D. americana) and feed them by hand. A "Stingray City" in the sea surrounding the Caribbean island of Antigua consists of a large, shallow reserve where the rays live, and snorkeling is possible, since the rays are used to the presence of humans.

SAVE ANIMALS
It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.
