The killer whale appears to be an opportunistic feeder; diet may vary from one region to the next, among age and sex classes, and within years (Kirkevold and Lockard, 47). Accessed November 09, 2019. The apparent tro- phic diversification of type 1 individuals, and between types 1 and 2 is based on traits ( d 1 5 N values and tooth wear) indicative of ecological segregation within a sin- gle generation. The killer whale (scientifically known as orcinus orca) is a large oceanic marine mammal that is part of the toothed whale (odontoceti) suborder.. The killer whale (Orcinus orca), commonly referred to as the orca, and less commonly as the blackfish, is a toothed whale belonging to the oceanic dolphin family.

An Orcas largest cells can be the size of a Honda to the size of a school bus, depending on genetics. However, until recently scientists had not proved these different species of orcas in Antarctica existed, as they had not mapped the entire genome of killer whale mitochondria housing their DNA.

The distinctive colouration of killer whales is thought to provide camouflage when hunting. Killer whales, Orcinus orca, are top predators occupying key ecological roles in a variety of ecosystems and are one of the most widely distributed mammals on the planet.In consequence, there has been significant interest in understanding their basic biology and ecology. . They live in communities that are totally separate from one another, which means Alaskan orca are not hanging out with their Kiwi relatives. The killer whale or orca is a toothed whale.
