Habitat. Cosmopolitan in marine habitats but somewhat more abundant at higher latitudes and in near-shore waters, especially in regions of high productivity. The Killer Whale has been documented, on rare occasions, to move into river mouths. Most observations have been within 800 km of shoreline. The Killer Whale is less abundant in lower tropical latitudes and in the ice-pack zones of the high Arctic and Antarctic oceans. In the Canadian Arctic Ocean, however, the Killer Whale is becoming seasonally more abundant as pack-ice extent and duration decline with global climate change. Resident, transient, and offshore forms of Killer Whales are most well known from populations on the north-western coast of North America, including the Aleutian Islands, and there is good evidence to suggest that, in that area at least, they may each warrant full species status. Resident Killer Whales are the most near-shore distributed of the three forms, given that they feed primarily on salmon migrating into freshwater areas to spawn. The type B Killer Whale is found primarily in Antarctic regions, usually among ice floes concentrated around the Antarctic Peninsula, although their distribution may extend up to the Falkland Islands and New Zealand. The type CKiller Whale appears to be restricted to Antarctic waters and prefers the pack-ice habitats in eastern Antarctica. The recently described type D Killer Whale is subantarctic and is most abundant between 40 ° S and 60 ° S.
