In Depth

       ‬Otodus was bigger than any other carnivorous fish in the sea today,‭ ‬being one and half times bigger than the largest recorded great white shark.‭ ‬This large size however does not mean that Otodus was an apex predator as it would have had to share the seas with other predators such as Basilosaurus,‭ ‬an eighteen metre long predatory whale that looked more like an ancient mosasaur.‭ ‬Still,‭ ‬Otodus would have been able to hold its ground against most other predators and could have taken everything from large fish to smaller mammals.
