Livyatan is an extinct genus of macroraptorial sperm whale containing one known species: L. melvillei.The genus name was inspired by the biblical sea monster Leviathan, and the species name by Herman Melville, the author of the famous novel Moby-Dick about a white bull sperm whale.
All species are known by at least a skull, and are informally grouped without a family designation. They were all likely the apex predator of their habitats, comparable to the modern day killer whale (Orcinus orca), and achieved great lengths, with one species—Livyatan—measuring about 13.5–17.5 m (44–57 ft).

The cheek teeth have well-developed accessory denticles.

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.

A third type of killer whale roams the Pacific, but less is known about it; these offshore whales live farther out and prey on sharks and other large fish. A recent study found evidence of another ...
