Lar Gibbon Characteristics

White Handed Gibbon

The lar gibbon[1] (Hylobates lar), also called the white-handed gibbon, is another endangered mammal in the gibbon family, Hylobatidae.

  • It is among the best-known gibbons and is occasionally kept in captivity. Lar gibbons have a two-tone coat.
  • They sport a dark coat that ranges from gray to black to tan or a light coat from light cream to tan.
  • The bare face is encircled by a very short white or light-colored fur ring, and the hands and feet are white.
  • Their elongated forelimbs, feet, and hands are used in their unique brachiation adaptations, which is their primary mode of locomotion through the treetops.
  • Lar gibbons do not have a tail. Male species measure 43.5 to 58.4 cm, and female species 42 to 58 cm. Males weigh from 5 to 7.6 kg and females from 4.4 to 6.8 kg.

Lar Gibbon Facts

  • Home territories are defended in encounters between groups and areas where domains overlap.
  • Lar gibbons use vocalization for intra-specific communication. Normal duets are based on territoriality, signaling nearby groups that pose a threat.
  • These gibbons are auto- and allo-grooming animals. On average, they spend 10 hours per day allo-grooming.
  • Lar gibbons communicate with conceptual songs, which are combinations of solos and/or duets performed by closely related pairs.
  • Although this species is very mobile, it does not gain security during this fixed period as it may fall asleep and not wake up until a predator is upon them.
