It is plausible that the adult megalodon population off the coast of Peru targeted primarily cetothere whales 2.5 to 7 meters (8.2 to 23 ft) in length and other prey smaller than itself, rather than large whales in the same size class as themselves.

The silhouettes shown here show O. megalodon as a robust Lamnid-like shark and are based on the estimated dimensions proposed by Cooper et al. and a life restoration by Oliver Demuth. [1] However, due to the limited information on life appearance, other body plans have been proposed, and O. megalodon could have looked substantially different in ...
