The killer whale or orca (Orcinus orca), or less commonly, blackfish, is the largest species of the dolphin family. It is found in all the world’s oceans, from the frigid Arctic and Antarctic regions to warm, tropical seas. Some killer whale populations feed mostly on fish while others hunt sharks and marine mammals, including sea lions, seals, walruses and even large whales. Fish-eating killer whales in the North Pacific have a complex but extremely stable system of social grouping. Unlike any other mammal species whose social structure is known, resident killer whales of both sexes live with their mothers for their entire lives. Therefore, killer whale societies are based around matrilines consisting of a single female (the matriarch) and her descendants. The sons and daughters of the matriarch form part of the line, as do the sons and daughters of those daughters. The average size of a matriline is nine animals. The resident killer whales’ diet consists primarily of fish and sometimes squid, and they live in complex and cohesive family groups. Pods possess lifelong family bonds, often living in large matrilineal groups and vocalizing in highly variable and complex dialects.
P.S. My daughter tells me that my water pattern looks like “The northern lights”. Pretty cool! I would like to say I did it on purpose but I won’t lie, it was purely accidental.:giggle:
