The 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, they are found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
A5 Pod is a name given to a group of orcas found off the coast of British Columbia, Canada. It is part of the northern resident population of orcas—a name given to the fish-eating orcas found in coastal waters ranging from mid-Vancouver Island in British Columbia up through Haida Gwaii and into the southeastern portions of Alaska. The orcas of the Northern Resident community are divided into vocally distinctive clans known as the A clan, the G clan, and the R clan. Members of the A5 Pod belong to the A clan. As of 2013, A5 Pod consisted of 10 members.
Corky II, often referred to as just Corky, is a female captive orca from the A5 Pod of northern resident orcas. At approximately the age of four, Corky was captured from Pender Harbour off the coast of British Columbia on 11 December 1969. She has lived at SeaWorld San Diego in San Diego, California since 21 January 1987. As of 2024, she is the oldest and longest kept captive orca. SeaWorld San Diego celebrates her birthday on 1st January every year.
Katina is a female orca who lives at SeaWorld Orlando in Florida. She was captured off Iceland at approximately three years of age on 26 October 1978. She is the most successful breeding female orca in captivity. SeaWorld Orlando celebrates her birthday on 1 June every year.
Ramu III was an Orca who resided at the now-defunct Windsor Safari Park in Berkshire, England between 1970 and 1976, and later, at SeaWorld San Diego in California between 1976 and 1986. An adult male, Ramu was caught on 8 August 1970, after his pod of eighty orcas was 'corralled' during the Penn Cove capture in Penn Cove, near Coupeville, Washington, United States. At capture, Ramu was 13.32 ft long and a member of the Southern Resident Killer Whales' L-pod. It is assumed his family members still survive in the Salish Sea and in nearby Pacific coastal waters.
Old Tom was a male orca who cooperated with and assisted whalers in the port of Eden, New South Wales, on the southeast coast of Australia. Old Tom was believed to be the leader of a pod of orcas which helped the whalers by herding baleen whales into Twofold Bay. This pod was also known as "the killers of Eden".
Springer, officially named A73, is a wild orca from the Northern Resident Community of orcas, which frequents the waters off the northern part of Vancouver Island every summer. In January 2002, Springer, then a calf developmentally equivalent to a human toddler, was discovered alone and emaciated some 250 miles from the territory of her family. Experts identified Springer by her vocal calls that are specific to her family, or "pod," and by examining photographs of her eye patch. They were also able to determine where Springer's pod was currently located.
Dozens of orcas are held in captivity for breeding or performance purposes. The practice of capturing and displaying orcas in exhibitions began in the 1960s, and they soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness, and sheer size. As of 24 March 2024, around 55 orcas are in captivity worldwide, 33 of which were captive-born. At that time, there were 18 orcas in the SeaWorld parks.
A4 pod is a killer whale family in British Columbia. 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. The community is made up of three clans known as A, G and R clans, each possessing a distinctive dialect and consisting of several related pods. A4 pod belongs to the biggest clan, A clan.
Michael Andrew Bigg was an English-born Canadian marine biologist who is recognized as the founder of modern research on killer whales. With his colleagues, he developed new techniques for studying killer whales and, off British Columbia and Washington, conducted the first population census of the animals anywhere in the world. Bigg's work in wildlife photo-identification enabled the longitudinal study of individual killer whales, their travel patterns, and their social relationships in the wild, and revolutionized the study of cetaceans.
The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean. The southern resident orcas form a closed society with no emigration or dispersal of individuals, and no gene flow with other orca populations. The fish-eating ecotype was historically given the name 'resident,' but other ecotypes named 'transient' and 'offshore' are also resident in the same area.
A1 pod is a killer whale family in British Columbia. It currently consists of 3 matrilines and 20 members and is the most commonly encountered pod in the Northern resident killer whale community. This community is found in coastal waters ranging from mid-Vancouver Island up through the Queen Charlotte Islands, although A1 pod has yet to be seen this far north. The community is made up of three clans known as A, G and R clans, each possessing a distinctive dialect and consisting of several related pods. A1 pod belongs to the biggest clan, A clan.
Alexandra Bryant Hubbard Morton is an American and Canadian marine biologist best known for her 30-year study of wild killer whales in the Broughton Archipelago in British Columbia. Since the 1990s, her work has shifted toward the study of the impact of salmon farming on Canadian wild salmon.
Granny, also known as J2, was a female orca of the J pod of southern resident orcas notable for her long life. Early estimates placed her birth in 1911, putting her at 105 years old at the time of her death. However, this estimate was later theorized to have been based on mistaken information and more recent studies put her at 65–80 years old. If she was 105, she would have been the oldest known orca at the time of her death. Granny lived in the northeast Pacific Ocean and coastal bays of Washington state and British Columbia. She was last seen on October 12, 2016, and was considered deceased by The Center for Whale Research in January 2017.
Tahlequah, also known as J35, is an orca of the southern resident community in the northeastern Pacific Ocean. She has given birth to three known offspring, a male (Notch) in 2010, a female (Tali) in 2018, and another male (Phoenix) in 2020. Her second calf, Tali, died shortly after birth and J35 carried her body for 17 days in an apparent show of grief that attracted international attention.
Northern resident orcas, also known as northern resident killer whales (NRKW), are one of four separate, non-interbreeding communities of the exclusively fish-eating ecotype of orca in the northeast portion of the North Pacific Ocean. They live primarily off the coast of British Columbia (BC), Canada, and also travel to southeastern Alaska and northern Washington state in the United States. The northern resident population consists of three clans 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.
Walter the Whale (Skana) was a star orca (killer whale) during the early era of captive orcas in the 1960s. In 1967, following the death of Namu, the only other established star orca was Shamu. Walter the Whale was the orca's advertised name at first, but she was later renamed Skana.
Orcas or killer whales have a cosmopolitan distribution and several distinct populations or types have been documented or suggested. Three to five types of orcas may be distinct enough to be considered different races, subspecies, or possibly even species. The IUCN reported in 2008, "The taxonomy of this genus is clearly in need of review, and it is likely that O. orca will be split into a number of different species or at least subspecies over the next few years." Although large variation in the ecological distinctiveness of different orca groups complicate simple differentiation into types. Mammal-eating orcas in different regions were long thought likely to be closely related, but genetic testing has refuted this hypothesis.
The waters of the Salish Sea, on the west coast of North America, are home to several ecologically distinct populations of orcas. The area supports three major ecotypes of orcas: northern residents, southern residents, and transients. A fourth ecotype, the offshore orcas, occasionally venture into nearshore waters. Little to no interaction occurs between the different ecotypes. Resident and transient orcas have not been observed interbreeding, although occasional brief interactions occur.
