Great white shark.

The great white shark is the world's largest known predatory fish. 
It has 300 teeth, yet does not chew its food. 
Sharks rip their prey into mouth-sized pieces which are swallowed whole. 

The shark’s heavy body allows it to swim for long periods of time, and then suddenly switch to high speed bursts in pursuit of prey—sometimes leaping out of the water. 
It feeds on a vast selection of prey, from small fish to large seals and dolphins.
They are considered vulnerable.
