Orca

The killer whale, also called the orca, is a large toothed whale with a streamlined black-and-white body. White coloration extends from the chin along the underside, with an additional white patch above each eye and a gray saddle behind the dorsal fin. Adult males average about 8 m and possess an erect dorsal fin reaching 1.8 m; females average about 7 m and have a shorter dorsal fin. Males are larger overall and average approximately 7,200 kg.

Killer whales occur in every ocean, from tropical seas to polar pack ice, although they often favor colder water. They inhabit both coastal and open-ocean environments and may dive to around 300 m. Highly social, they live in multigenerational maternal pods whose members coordinate movement, share prey, and teach hunting skills. Each pod maintains a distinctive vocal dialect, while clicks support echolocation. Diet varies among populations and can include fish, sharks, squid, seals, sea lions, dolphins, whales, turtles, seabirds, and otters. (Animal Diversity Web)
