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.
English: Various size estimates of Livyatan melvillei, an extinct macroraptorial sperm whale, compared to the extant sperm whale (Physeter macrocephalus). • Livyatan was described by Lambert et al. (2010) and is primarily known from a large, fairly complete ~3 metres (9.8 ft) long skull, MUSM 1676.
However, given their size, they probably did not need to hunt in groups. 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.

Leviathan also figures in the Hebrew Bible as a metaphor for a powerful enemy, notably Babylon (Isaiah 27:1). Some 19th-century scholars pragmatically interpreted it as referring to large aquatic creatures, such as the crocodile. [4] The word later came to be used as a term for great whale and for sea monsters in general.
Some Neogene rorquals were comparable in size to modern huge relatives. Parabalaenoptera was estimated to be about the size of the modern gray whale, [113] about 16 m (52 ft) long. Some balaenopterids perhaps rivaled the blue whale in terms of size, [113] though other studies disagree that any baleen whale grew that large in the Miocene. [114]
The sperm whale is the largest toothed whale and is among the most sexually dimorphic of all cetaceans. [35] Both sexes are about the same size at birth, [11] but mature males are typically 30% to 50% longer and three times as massive as females. [36] [37] Newborn sperm whales are usually between 3.7 and 4.3 meters (12 and 14 ft) long. [38]
