Atlantic Humpback Dolphin

Sousa teuszii

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The Atlantic humpback dolphin is one of the most threatened cetaceans in the world. It lives hard against the West African coast, almost always less than three kilometres from land and in water under twenty metres deep, which exposes it directly to artisanal fishing nets. It owes its name to an elongated hump on the back on which a small dorsal fin sits. Its subpopulations are highly fragmented and some are already down to a few dozen animals.

Fun facts

  • On the Banc d'Arguin in Mauritania, cooperative fishing has been documented between these dolphins and the Imraguen fishermen, who beat the water with sticks so that the dolphins drive the mullet shoals towards the nets.
  • It is a strictly coastal cetacean: it almost never ventures more than a few kilometres from shore, which makes it the large cetacean most exposed to human activity in Africa.
