The killer whales employed a tail outward and tail-slapping defensive position against the bull sperm whale similar to that used by female sperm whales against attacking killer whales. [206] However, at some potential feeding sites, the killer whales may prevail over sperm whales even when outnumbered by the sperm whales.
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.

Macroraptorial sperm whales occupied the same niche as killer whales (Orcinus orca). Using their large and deeply rooted teeth, wide-opening jaws, and great size, they likely fed on a variety of sea life, including fish, cephalopods, seals, and small whales and dolphins, occupying a niche similar to the modern day killer whale (Orcinus orca).
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races , [ 1 ] subspecies , or possibly even species [ 2 ] (see species problem ).
I. Grampus (Orcinus orca commonly known as the orca or killer whale). Melville states that this species is known for its loud blowing and is well known among whalemen. According to Melville, it swims in herds and is never regularly hunted, although it has considerable oil that is good for producing light.
