Question

why shark and crocodile have sharp teeth by the idea of pressure?

Answer 1

Answer:

Most of them need powerful jaws and sharp teeth to kill their prey. ... In most species the teeth are triangular or pointed, with sharp tips and knifelike, jagged edges—a sure sign of a hunter. In a typical shark attack, if the prey is too big to eat in one bite, the shark will clamp its teeth on the victim's body.
