The Delacour’s langur[1], also known as Delacour’s Lutung, is an endangered Lutung native to northern Vietnam.
- Delacour’s langurs are known for the distinct patches of white fur on their thighs that contrast with their black fur.
- Females also have a patch of white fur close to their genitalia. Like its relatives in the Langur and Lutung families, the Delacour’s langur has tufts of gray hair on its cheeks and a tuft on its head.
- Like many of its relatives, baby Delacour’s langur has bright orange fur for the first 4 months of life.
- This odd feature has been the subject of several scientific theories and studies.
- You might think bright colors would make the baby more visible to predators, but the color seems to help babies.
