A5 Pod is a name given to a group of orcas (Orcinus orca) 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. Over time, studies showed that these congregations of orcas did not make up a complete, distinctive pod. Rather, they were matrilines - a mother and her offspring up to the fourth generation. However, matrilines within a pod frequently socialize with one another, more so than with orcas from another pod - thus still making up a distinct community, and so perpetuating the use of the pod naming. Naming When studies first began, it was assumed all orcas traveling together were part of the same pod. Initially, males were also thought to lead harems of females and their young. Some pods were therefore named after a distinctive male while others were named after other distinctive individuals. The A5 Pod itself was named after a male orca, A5, also known as Top Notch. He was part of the A9 matriline, of which his mother, A9 (also known as Scar or Eve) was the leader. The A5 pod is currently made up of three matrilines. The line of A9 has died out with her sons, A5 (Top Notch) and A26 (Foster). She had no surviving daughters to carry on her line, although the matriarch of another family, A8 (Licka) was suspected to be her daughter. A9 washed up on a beach in Johnstone Strait in November 1990, her stomach containing 5 litres of fish bones representing 13 different species. Other whales in the pod include A23 (Stripe) and A60 (Fife). Capture As a whole, A5 Pod was captured several times during the 1970s, in order to take young orcas into aquariums around the world. Almost an entire generation of orcas was taken from different families of the A5 pod. A female, Corky, is the only orca from these captures still alive, and the only surviving member of those
