Hector's Dolphin

Cephalorhynchus hectori

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

Hector's dolphin is the smallest marine dolphin in the world and is endemic to New Zealand. It is told apart by its rounded dorsal fin, shaped like a mouse's ear, unique among the dolphins. It lives in small groups in murky coastal waters, where it hunts fish and squid near the bottom. Its northern subspecies, the Māui dolphin, is one of the most threatened cetaceans on the planet, with fewer than a hundred individuals. Accidental capture in gillnets is its main threat.

Fun facts

  • conservaciónIt is one of the smallest marine dolphins in the world and one of the most threatened cetaceans, confined to the coastal waters of New Zealand.
  • Its rounded, blunt dorsal fin is unique among all the dolphins and allows the species to be identified at a single glance.
  • It breeds extremely slowly: the females do not calve until they are seven or eight and have one calf every two or three years, so the death of a few animals a year in nets is enough to crash a population.
