Phayre's Leaf-monkey

Trachypithecus phayrei

Endangered

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

Spotted something wrong?

Phayre's leaf monkey or spectacled langur is a primate with dark grey fur and characteristic white rings around the eyes and lips, which make it look as though it were wearing glasses. It lives in groups in the forests of north-eastern India, Bangladesh, Myanmar and northern Indochina. It is folivorous and digests mature leaves in a compartmented stomach. Forest fragmentation and hunting have led to its classification as endangered.

Fun facts

  • The white rings around its eyes and lips give it the look of wearing glasses and a mask that makes it unmistakable among the Asian langurs.
  • Its young are born a bright golden orange that contrasts with the grey of the adults, and every female in the group takes part in looking after them, a strongly marked form of cooperative care in this species.
