African Manatee

Trichechus senegalensis

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The African manatee is the only sirenian in Africa and the least known of the three manatees. It occupies an enormous stretch of the Atlantic coast, from Mauritania to Angola, and travels up the great African rivers, especially the Niger, more than 2,000 kilometres from the sea. It is a herbivore but, unlike its American relatives, it also takes molluscs and fish caught in nets. It feeds mainly at night and rests by day in deep water. Poaching, nets and hydroelectric dams are its greatest threats.

How to help

The african manatee is classified as vulnerable. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 6 protected areas — one reason why protecting these places matters for its conservation.
