Killer Whale

 
Introduction:

The Killer Whale, Orcinus orca, is the largest member of the dolphin family.

Identification:

The Killer Whale is a strikingly marked animal characterised by a body pattern of dramatically contrasting areas of intense black and white. The rounded head, indistinct beak, large pointed teeth and prominent upright dorsal fin complete what is considered one of the oceans most impressive mammals.

Size:

9 m, 5 tonnes

Distribution:

The Killer Whale is found in all oceans and seas of the world usually in family groups. They occur in most
habitat types from coastal areas to the deep ocean waters, from the tropics to polar regions.

Feeding and Diet:

These animals are serious meat eaters and one of the most efficient large predators of the ocean. A cooperative hunter, they often work in packs, and will take a broad range of vertebrates including whales, seals, penguins, fish, sea otters, and turtles. Killer Whales have marked territorial behaviour and home ranges. Their prey is determined by what is available in their home ange but they also seek out areas of seasonal abundance such as seal pupping sites.

Conservation Status:

The Killer Whale has never been the target of serious commercial hunting so the species worldwide is secure. There is some concern about depletion of individual populations and disruption to social structure from captures for the oceanarium trade and limited hunting in some parts of Asia, Northern Europe and the West Indies.
