Indochinese Gray Langur Distribution
Indochinese Grey Langur Characteristics
The Indochinese gray langur (Trachypithecus crepusculus) is a species of Lutung native to Southeast and East Asia.
- The Indochinese gray langur’s body and tail are light bluish-gray, with ventral fur ranging from silver-gray to white.
- The facial skin is dark gray with lighter pigmentation in a ring around the eyes and patches of unpigmented skin in the middle of the lower and upper lips.
- They have a thick crest on their heads and a long tail of about 83 centimeters.
- Males and females of this species are similar in size, weighing between 6.4 and 7.1 kilograms and having a head-to-body length of around 51 centimeters.
- Females have a distinctive “pudenda” of white fur and pale skin in front of the callosities.
Indochinese Grey Langur Facts
- This species was once thought to be conspecific with the Phayre’s leaf monkey (Trachypithecus phayrei). Still, a 2009 study found it to be a separate species.
- Indochinese gray langur monkeys are pretty shy and often run away when threatened.
- Group size can be up to 20 individuals and may consist of more than one male with several females and their young.
- Unlike langurs that live in karst forests, which have a primarily terrestrial lifestyle, the Indochinese gray langur inhabits old-growth evergreen forests.
- The population of this species is believed to be only about 2, 400-2, 500 adult individuals. It is threatened by habitat destruction and hunting, particularly in Vietnam and Laos.
