Killer Whales: the natural history and genealogy of Orcinus orca in British Columbia and Washington (2nd ed.). Vancouver, BC: UBC Press. ISBN 9780774808002. Olesiuk, P. F.; Bigg, M. A.; Ellis, G. M. (1990). "Life History and Population Dynamics of Resident Killer Whales (Orcinus orca) in the Coastal Waters of British Columbia and Washington State".
Resident (fish-eating) orcas: The curved dorsal fins are typical of resident females. Resident: These are the most commonly sighted of the three populations in the coastal waters of the northeast Pacific. Residents' diets consist primarily of fish [6] and sometimes squid, and they live in complex and cohesive family groups called pods. [7]
Johnstone Strait is the summer home to a large number of resident killer whales, and includes the Robson Bight/Michael Bigg Ecological Reserve. Although he is best known for his work with killer whales, Bigg spent most of his career studying other marine mammals. He researched northern fur seals in British Columbia and the Pribilof Islands of ...
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Orca vs. whale shark The researchers’ analysis revealed exactly how the killer whales, often hunting as a group, subdue the whale shark. First, the orcas use their bodies to hit a whale shark at ...
Granny (southern resident J2) was the oldest fully authenticated wild orca on record, at least 65 years old at the time of her presumed death in October 2016. Her exact age will never be known; she was first sighted in 1967, during an orca capture, and was considered too old for capture due to her age (estimated at more than 40, due to her ...
The northern resident population consists of three clans (A, G, R) that consists of several pods with one or more matrilines within each pod. The northern residents are genetically distinct from the southern resident orcas and their calls are also quite distinct.
As of March 2013, it consists of three matrilines and 15 members and is the family of Springer, the first orca to be successfully reintroduced to the wild after being handled by humans. A4 pod is part of the northern resident orcas found in coastal waters ranging from mid- Vancouver Island to southeastern Alaska up through Haida Gwaii (formerly ...
