Scientists believe that megalodon ate a variety of large fish and whales. It is estimated that it ate around 2,500 pounds of food each day to fuel its 77-ton, 60-foot-long body.
The megalodon had a mouth filled with teeth to eat its prey. There were a total of six rows of teeth, including rows of 24 on the top and 22 on the bottom of its jaws for an average total of 276 teeth in most specimens.
Scientists say that megalodon lived from 2 to 17 million years ago, although it is now extinct along with other giant mega-toothed sharks. Its closest living relatives include the mako and great white sharks.
