Where do killer whales live and why?

Answer 1

Killer Whales are found in all oceans and most seas, including (unusually for cetaceans) the Mediterranean and Arabian Seas. However, they prefer cooler temperate and polar regions. Killer whales also live south of Africa and Australia in the cold Arctic Seas and Tropics. In the winter the families of killer whales migrate to warmer waters. That's where their young are born. Although sometimes spotted in deep water, coastal areas are generally preferred to pelagic environments. The Killer Whale is particularly highly concentrated in the northeast Pacific Basin, where Canada curves into Alaska as well as the Johnstone Straight area and Washington state. They are making a bigger presence in California too. There are also large populations off the coast of Iceland and off the coast of northern Norway. They are regularly sighted in Argentina and the Antarctic waters right up to the ice pack and are believed to venture under the pack and survive breathing in air pockets like the beluga does. In the Arctic, however, the species is rarely seen in winter, as it does not approach the ice pack. It does visit these waters during summer. Killer whales live in the cold waters of the Northern Pacific & Atlantic Oceans & the Arctic Sea. They are often found off the Western coast of North America, near Alaska and British Columbia.
