Streamlined and muscular, megalodon had jaws over 2m wide. While megalodon could eat whatever it chose, its favourite food was whale. Other kinds of marine mammals such as seals and Odobenocetops were also on its menu.

Most of this shark's hunting was in the open sea (juveniles lived closer to shore). It attacked its prey near the surface, when it came up for air.

Megalodon could swim at high speed in short bursts so tended to rush its prey from beneath. Especially when tackling large species, it would first aim to disable its prey by injuring a flipper or the tail. Once unable to swim properly, the victim would be easy to finish off.
