Francois’ Langur

More Information

Physical Description

Adult Francois’ langurs have black fur with a white stripe stretching from ear to ear acros their jawline, as well as a black crest atop their head. Young langurs are orange at birth, which may encourage adult females to care for and keep track of them. These primates, which feed primarily on leaves, have a multi-chambered stomach that helps them get the most out of their low-nutrient diet. Special bacteria lining their stomach also aid the process.

Interesting Fact 1

Francois’ langurs are threatened by logging, agriculture, hunting, and the illegal pet trade.

Interesting Fact 2

Females assist in caring for other langurs’ offspring, a behavior called alloparenting or “aunting.”

Interesting Fact 3

Males define and defend their territory with hoarse vocalizations.
