Livyatan (SciiFii)

The great killer sperm whale (Livyatan melvillei), also known as the Leviathan or the Moby-Dick, is a species of sperm whale that originally lived in the Pisco Formation of Peru during the the Miocene epoch (possibly Pliocene epoch as well), about 9.9–8.9 million years ago (mya) (but also around 5 mya if it also lived in the Pliocene), and was once extinct, but has since been brought back from extinction by SciiFii and introduced to the modern Indian and Pacific Oceans. It is a member of a group of hyper-predatory macroraptorial sperm whales (or "raptorial sperm whales") and is an apex predator, preying on other whales, seals, and so forth. Characteristic of raptorial sperm whales, greater killer sperm whale has functional, enamel-coated teeth on the upper and lower jaws, as well as several adaptations for hunting large prey. Its total length is normally around 13.5–17.5 meters (44–57 ft), similar to the modern sperm whale (Physeter macrocephalus), making it one of the largest predators to ever exist. The tallest teeth measures 36.2 cm (14.3 in), and is the largest tooth of any known animal, excluding tusks. It is distinguished from the other raptorial sperm whales by the basin on the skull, and how it spans the entire length of the snout. The spermaceti organ, contain in that basin, is used in echolocation and communication, and for ramming prey and other sperm whales. The original species of Livyatan may have interacted with the large originally extinct shark Megalodon (Carcharocles megalodon), competing with it for a similar food source. The conservation status of the great killer sperm whale is Least Concern due to successful conservation efforts.
