SAN DIEGO (CBS 8) - A week-old Francois' langur made its debut at the San Diego Zoo Thursday.
The langur - also known as a leaf monkey - held tightly to one of its relatives as its troop foraged and climbed around the exhibit.
Franois' langurs practice "alloparenting," meaning every family member participates in raising the infant.
Langurs are born with bright orange hair. Their coloring usually changes within the first six months to match the black color of their parents.
