Predators and prey. In addition to being the world’s largest fish, megalodon may have been the largest marine predator that has ever lived. (Basilosaurids and pliosaurs may have been just as large.) Megalodon was an apex predator, or top carnivore, in the marine environments it inhabited (see also keystone species).
Could a Megalodon kill a blue whale?
It fed on other big marine mammals, like whales and dolphins. It may have even eaten other sharks, according to Discovery. Researchers think the megalodon would first attack the flipper and tails of the mammals to prevent them from swimming away, then go in for the kill, according to the BBC.
