The killer whale or orca, is the largest of the dolphins, a
predator, feeding on fish, seals, and sometimes whales. Killer
whales attract tourists to Vancouver Island
Killer Whale or also known as the Orca Whale often transit the
waters of Discovery Passage between Vancouver Island and Quadra
Island.
They are a mammal , a carnivore and can live up to 80 years of age.
They can measure up to 32 feet in length and can weigh up to 6 tons.
The size of a bus the killer whale is the world's most powerful
predator. They feast on marine mammals such as seals, sea lions, and
even whales, employing teeth that can be four inches (ten
centimeters) long. They are known to grab seals right off the ice.
They also eat fish, squid, and seabirds.
Though they often frequent cold, coastal waters, orcas can be found
from the polar regions to the Equator.
Killer whales hunt in deadly pods, family groups of up to 40
individuals. There appear to be both resident and transient pod
populations of killer whales. These different groups may prey on
different animals and use different techniques to catch them.
Resident pods tend to prefer fish, while transient pods target
marine mammals. All pods use effective, cooperative hunting
techniques that some liken to the behavior of wolf packs.
Whales make a wide variety of communicative sounds, and each pod has
distinctive noises that its members will recognize even at a
distance. They use echolocation to communicate and hunt, making
sounds that travel underwater until they encounter objects, then
bounce back, revealing their location, size, and shape.
Killer whales are protective of their young, and other adolescent
females often assist the mother in caring for them. Mothers give
birth every three to ten years, after a 17-month pregnancy.
Orcas are immediately recognizable by their distinctive black and
white colouring and are also intelligent and trainable.
