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. [70] Meanwhile, juveniles likely had a diet that consisted more of fish. [34] [74]
Members of the group include macropredators, generally of medium-large size, including the largest macropredatory shark ever, the extinct Otodus megalodon, as well as large planktivores. [ 2 ] Although some authors have argued that the Late Jurassic Palaeocarcharias should be considered the oldest known lamniform, this is disputed.

Prehistoric Predators is a 2007 National Geographic Channel program based on different predators that lived in the Cenozoic era, including Smilodon and C. megalodon.The series investigated how such beasts hunted and fought other creatures, and what drove them to extinction.
This is the size that Gottfried et al. (1996) list as the 'largest mature female' in their study. The smaller silhouette is scaled to 4.7 metres (15 ft), the size Gottfried et al. list as the 'smallest mature female'. On average, male great whites are smaller than females. [2] The largest size obtainable by the great white is controversial.

The hammer-like shape of the head means that hammerhead sharks can sweep for prey more effectively. The hammerhead sharks are a group of sharks that form the family Sphyrnidae, named for the unusual and distinctive form of their heads, which are flattened and laterally extended into a cephalofoil (a T-shape or "hammer").
The Lamniformes also include the extinct megalodon, Otodus megalodon. Orectolobiformes: They are commonly referred to as the carpet sharks, including zebra sharks, nurse sharks, wobbegongs, and the whale shark. Pristiophoriformes: These are the sawsharks, with an elongated, toothed snout that they use for slashing their prey.
