Bull shark



Bull shark
Bull shark is the 4th dangerous in the world . It lives in fresh water and saltwater. It is perfect killing machine . It's bite ever recorded in 919 psi.



Etymology

In India, the bull shark may be confused with the Sundarbans or Ganges shark. In Africa, it is also commonly called the Zambezi River shark or just Zambi. Its wide range and diverse habitats result in many other local names, including Ganges River shark, Fitzroy Creek whaler, van Rooyen’s shark, Lake Nicaragua shark.

Behavior

Bull sharks are able to regulate themselves to live in either fresh water or salt water. It is possible for the bull shark to live in fresh water for its entire life, but it has been observed that this does not happen for certain reasons, mostly due to reproduction. Young bull sharks will leave the brackish water in which they are born and move out into the sea in order to breed with bull sharks of the other sex. While theoretically, it may be possible for bull sharks to live in purely freshwater, it was observed that the bull sharks that were being experimented on had died within four years.

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.

 THE END

THANK YOU
