The northwestern woolly lemur or Sambirano woolly lemur ( Avahi unicolor ) is a primate species from the lemur group . It has only been considered a separate species from the western woolly lemur since 2000 .
Northwestern woolly lemurs reach a body length of 25 to 29 centimeters, plus a 33 centimeter long tail. Their weight is about 0.85 kilograms. Their thick, woolly fur is gray-brown on the upper side, and the belly is light gray. The long, bushy tail is gray-brown to red-brown in color. The hair on the face is shorter, which makes it contrast with the woolly hair on the head, but unlike Western woolly tarsier it is not whitish. The eyes are large, brown and surrounded by dark rings, the ears are small.
Like all lemurs, they live in Madagascar . Its distribution area includes the Sambirano region in the northwest of this island, but the exact dimensions are not known. Their habitat are more humid forests up to 700 meters above sea level. They are nocturnal tree dwellers that move vertically climbing and jumping. Otherwise nothing is known about their way of life, presumably it corresponds to that of the western woolly lemur.
Their degree of risk is also unclear. The IUCN lists the species under “too little data available” ( data deficient ).
