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.
Should the schizomid not retreat, it will lunge forward and seize its victim with its palps. [15] The prey is then subdued, and possibly taken to the shelter of a nearby crevice to be eaten. [ 15 ] The chelicerae dismember the prey item before the tissues are liquified into chyme and ingested via suction with the mouth.
Kogiidae is a family comprising at least two extant species of Cetacea, the pygmy (Kogia breviceps) and dwarf (K. sima) sperm whales.As their common names suggest, they somewhat resemble sperm whales, with squared heads and small lower jaws, but are much smaller, with much shorter skulls and more notable dorsal fins than sperm whales.

The sperm whale or cachalot [a] (Physeter macrocephalus) is the largest of the toothed whales and the largest toothed predator.It is the only living member of the genus Physeter and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus Kogia.

Scientists studying the sperm whales that live around the Caribbean island of Dominica have described for the first time the basic elements of how they might be talking to each other, in an effort ...
Physeter is a genus of toothed whales.There is only one living species in this genus: the sperm whale (Physeter macrocephalus). [2] Some extremely poorly known fossil species have also been assigned to the same genus including Physeter antiquus (5.3–2.6 mya) from the Pliocene of France, [3] and Physeter vetus (2.6 mya – 12 ka) from the Quaternary of the U.S. state of Georgia.

Male sperm whales are sexually mature at 11 to 12 meters (36 to 39 ft), and physically mature at about 15 to 16 meters (49 to 52 ft) in length, on average. Larger-than-average females have been generally recorded around 12 to 13 meters (39 to 43 ft), and larger-than-average males are usually stated to reach a maximum of about 18 to 19 meters ...
