Types Of Killer Whales
Killer Whales are not only the top predators in the sea but they are found all throughout the world’s oceans. They are more abundant in the colder waters of the Arctic, Norway and Alaska and have also been located in tropical and subtropical waters as well. They are most populous in the North Pacific Ocean where there are 3 main types – Offshore, Transient and Resident.
- Resident – these orcas are categorized into 3 subgroups – southern, northern, and Alaskan and their range is from Alaska to California.
- Transient – these killer whales live in small groups in coastal and offshore waters and are sometimes referred to as Bigg’s orcas. Their range is from the Arctic Circle to southern California.
- Offshore – these whales are generally found far from the shore in large groups and have the largest range out of the 3 types. Their range is from southern California to the Aleutian Islands in southern Alaska
These 3 main types of orcas are known as ecotypes and all differ in size, color, prey preferences, dialects, social groups, foraging techniques, and behaviors. While these are the main types, there are additional types that, depending on the region, also differ in their characteristics, appearances and behaviors.
