Otodus megalodon (whose species name, megalodon, derives from Greek and means 'large tooth') is an extinct species of giant shark that lived from the early Miocene to the early Pliocene, approximately 23 to 3.6 million years ago (Aquitanian to Zanclean), with large fossil teeth demonstrating its cosmopolitan distribution. In the past, it was thought that O. megalodon was a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias), but subsequent studies have reclassified it within the extinct family Otodontidae, which diverged from the lineage of the great white shark during the Early Cretaceous.

Estimates of the megalodon's size vary depending on the method used, with maximum total length projections ranging from 14.2 to 20.3 meters.
