The Laotian leaf monkey inhabits forested areas on steep hillsides, living on steep, often nearly vertical cliffs of karst limestone. Such hills can provide primates with a safe haven from hunting and other human activities.

This endangered species lives at altitudes up to 1,500 meters, in trees and on land. The main food is fresh young leaves of various tree species. It usually forms small groups of 2-15 individuals, but larger groups can sometimes be seen.

The Laotian leaf monkey is accustomed to roosting in limestone caves, crevices and cliff rocks at night, while other species of the same genus generally roost in trees. Most Vietnamese leaf monkeys sleep alone, although they sometimes sleep close to each other. The habitat usually faces west or southwest, is heated by the afternoon sun, and seeks shelter from the cold north wind in winter.

Listed in the 2008 Red List of Endangered Species of the World Conservation Union (IUCN) ver 3.1 - Vulnerable (VU).

Listed in the CITES Appendix II of the Washington Convention on International Trade in Endangered Species.

Form

The Laotian leaf monkey has a head and body length of 50-66 cm, a tail length of 81-87 cm, and a body weight of up to 8.7 kg. It is a leaf monkey with black hair. There is a unique white mark on the face, including some light whiskers, which extend from the corners of the mouth to above the ears and end at the nape of the neck. The fur on the rest of the head is black, with a distinct and uniquely shaped crest. The body fur is very smooth. Newborns are yellow-orange, but this color fades within a few weeks, and by 3 months, it is completely black as an adult monkey.
