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.
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.
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. [91] Some attained gigantic sizes, such as Livyatan, estimated between 13.5 to 17.5 meters (44 to 57 ft).
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 ...
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 ...
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...
In this episode, Brygmophyseter, which was referred to as the "biting sperm whale", was portrayed as being able to weaponize sonar in order to stun prey, and to have traveled in pods like the modern-day killer whale. The pod was attacked by a megalodon, which seemingly had a similar size to the whales. When the megalodon severely wounded one of ...
