Sarawak Surili Characteristics

The Sarawak surili[1], also known as Cross-marked Langur, is a monkey species in the Cercopithecidae family.

  • It is native to the island of Borneo in Southeast Asia. Like all genus Presbytis, Sarawak surili has a short muzzle and poorly developed eyebrows.
  • They have long front and relatively long hind legs, consistent with their preferred mode of locomotion, brachiation, and jumping.
  • The Sarawak surili exhibits sexual dimorphism in coat color as the female has a brown coat with an underside lighter than the back.
  • The male has a dark gray coat with a white underside.

Sarawak Surili Facts

  • The Sarawak surili was once considered widespread but has declined significantly due to habitat and loss persecution.
  • It is considered one of the rarest primates in the world. It has been listed as critically endangered by the IUCN.
  • These primates live in troops of a single male with 5-17 females.
  • The Sarawak Surili engages in 3 or 4 foraging and feeding fights throughout the day.
  • They travel among the upper treetops, retreating at night to high ridges and trees to roost.
