Hose’s Langur Characteristics

The Hose’s langur[1] (Presbytis hosei) is a primate species in the Cercopithecidae family native to the island of Borneo, which includes Brunei, Kalimantan (Indonesia), and eastern Malaysia.

  • Hose’s langur is a relatively small and slender primate, characterized by a high forehead and a prominent forward-sloping crest in the center of the crown.
  • Coat color varies between subspecies but is gray mainly on the back, white on the chest and stomach, and blackish on the feet and hands.
  • The face is pink, with a distinctive black stripe marking each cheek.
  • Babies are easy to tell apart as white with black lines down their backs and shoulders.
  • Groups (probably adult males) often emit a unique gurgling vocalization.

  • This tree-dwelling monkey moves primarily through the intermediate levels of the forest canopy, and to descend to visit natural mineral springs.
