Saola

Pseudoryx nghetinhensis

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The saola is a bovid of the forests of the Annamite Range, with two straight, sharp horns that can be more than 50 centimetres long and striking white markings on the face. It was discovered in 1992 and was the first new large mammal known to science in more than half a century. It is so rare and so elusive that no biologist has ever seen a live animal in the wild: everything known about it comes from camera traps, from a few captured animals that died in captivity and from trophies kept by villagers.
