This is a Red Ruffed Lemur, Varecia rubra (Primates - Lemuridae), a Critically Endangered species with a range restricted to the remaining primary forests of the Masoala Peninsula and the region immediately north of the Bay of Antongil in northeastern Madagascar.
Varecia rubra gets its common name from a ruff of rust red hair that flanks its black face like sideburns. The black face matches the black hands, feet, belly, and tail. Most of the body is covered by a soft, thick, rust red coat, except for a patch of white fur at the back of the head.
In just six years this species went from Endangered (1990) to Critically Endangered (1996).
Rare Red Ruffed Lemur Born at San Diego Zoo. The infant is the first of its species
to be born at the facility in 13 years and currently tips the scale at 9.2 ounces
(260 grams). Keepers have officially named the lemur “Ony,” which means river
in the native Malagasy language. Watch the full video on YouTube.
