Megalodon were contemporaneous with whale-eating toothed whales (particularly macroraptorial sperm whales and squalodontidae), which were also probably among the era's apex predators, and provided competition. [92] Some attained gigantic sizes, such as Livyatan, estimated between 13.5 to 17.5 meters (44 to 57 ft).
It was a member of a group of macroraptorial sperm whales (or "raptorial sperm whales") and was probably an apex predator, preying on whales, seals and so forth. Characteristically of raptorial sperm whales, Livyatan had functional, enamel -coated teeth on the upper and lower jaws, as well as several features suitable for hunting large prey.

In the seas millions of years ago, whales were regularly hunted.Megalodons, bus-sized sharks, are believed to have been dominant ocean predators some 20 to 3.6 million years ago. The now extinct ...
Marine mammals likely constituted a big part of megalodon's menu, so with it gone, they were free to thrive. Observations indicate that in the years since the mega-shark's extinction, baleen ...
There is also potential evidence that Otodus hunted raptorial sperm whales; a tooth belonging to an undetermined 4 m (13 ft) physeteroid closely resembling those of Acrophyseter discovered in the Nutrien Aurora Phosphate Mine in North Carolina suggests that a megalodon or O. chubutensis may have aimed for the head of the sperm whale in order to ...
The ancient shark, which grew up to 65ft long and weighed over 50 tons, ate sperm whales by ripping off their heads with its huge teeth, a new study has shown. The ancient shark, which grew up to ...
Livyatan probably targeted medium-sized whales ranging in size from 7–10 m (23–33 ft). Macroraptorials probably competed with the extinct giant shark megalodon for the same food sources. [7] [10] [11] [12] In sperm whales, the supracranial basin holds the spermaceti organ, a series of oil and wax reservoirs which aids in echolocation.
