Māui dolphin

Māui dolphin, Maui's dolphin, or popoto (Cephalorhynchus hectori maui) is a subspecies of the Hector's dolphin (Cephalorhynchus hectori)—New Zealand's only endemic cetacean. Māui dolphins are only found off the west coast of New Zealand's North Island, and are now one of the rarest and smallest dolphin subspecies globally. A 2021 report issued by the New Zealand government suggests the population rests at 54 individuals, but when taking into account recent mortalities, the population could sit at fewer than 50 individuals. Both the Māui dolphin and South Island Hector's dolphin are threatened by commercial fisheries, including set-netting and trawling, recreational netting, and disease including toxoplasmosis and brucellosis. Low food availability may also be an issue for Māui dolphins, which may increase their susceptibility to climate change.
