Hector's dolphin

Hector's dolphin (Cephalorhynchus hectori) is one of six dolphin species belonging to the genus Cephalorhynchus. Hector's dolphin is the only cetacean endemic to New Zealand, and comprises two subspecies: C. h. hectori, the more numerous subspecies, also referred to as South Island Hector's dolphin, and C. h. maui, the critically endangered Māui dolphin that is found off the West Coast of New Zealand's North Island.

Distinctive features of the species include a rounded dorsal fin, grey, white, and black coloration, and a stocky body shape. Their lifespan is typically around 20 years, and the species favours shallow coastal waters around the South Island, where they live in small groups and use echolocation clicks to communicate.
