The killer whale is a cosmopolitan creature, having been observed in oceans all over the world. They tend to concentrate in colder regions and are found in all of Canada’s oceans, as well as occasionally in Hudson Bay and in the Gulf of the St. Lawrence. In British Columbia, they have been seen throughout almost all marine areas including many inlets and narrow channels.
DIET
Throughout their world-wide range, killer whales eat a wide variety of prey, including squid, fish, sea turtles, sea birds, sea and river otters, sea lions, penguins, dolphins and other large cetaceans, such as the blue whale.
BEHAVIOUR
Females don’t give birth to their first calf until they are about 15 years old and they calve only once every five years on average. While whales have no natural predators, calves are vulnerable during infancy.
