Bengal Slow Loris

Nycticebus bengalensis

Endangered

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

Spotted something wrong?

The Bengal slow loris is the largest of the slow lorises and the one with the widest range, from north-eastern India to Vietnam. It is a nocturnal primate of deliberate, silent movements, with enormous eyes and a tapetum lucidum that reflects light. It feeds on tree gums and saps, nectar, fruit and insects. Deforestation and above all its capture for the pet trade and for traditional medicine have taken it to the endangered category.
