The Masoala fork-marked lemur (Phaner furcifer), also known as the eastern fork-marked lemur or Masoala fork-crowned lemur, is a species of lemur found in the coastal forests of northeastern Madagascar. It is a small nocturnal animal with large eyes, greyish fur and a long tail.
P. furcifer is a specialist feeder on the gum that exudes from insect holes on the surface of certain trees, but it supplements its gum diet with insect prey. This primate is monogamous and a single offspring is born in November or December. It is declining in numbers due to habitat destruction, and the International Union for Conservation of Nature has assessed its conservation status as being "vulnerable".
The Masoala fork-marked lemur is so-called because the black stripe along its spine divides on the crown, the two forks continuing on either side of the head to the eye and along either side of the muzzle. The rest of the pelage is some shade of reddish or brownish grey. The head-and-body length is in the range 227 to 285 mm (9 to 11 in), with a tail of 285 to 370 mm (11 to 15 in). This lemur typically weighs between 300 and 500 g (11 and 18 oz).
This lemur is endemic to northeastern Madagascar. Its range extends from the Masoala Peninsula southwards to Toamasina and it is present at altitudes up to about 1,000 m (3,300 ft). It occurs in moist lowland forests.
The social system of the Masoala fork-marked lemur has been described as pre-gregarious. Some adults live as monogamous couples, sharing the same nest hole by day but moving about independently for at least part of the night (the male often follows a few metres behind the female), but a few live as solitary bachelors or have ranges overlapping more than one female. The average size of a female territory is 4 hectares (9.9 acres) with a male territory averaging 3.8 hectares (9.4 acres). The lemurs sometimes gather at the places where the territories overlap; there is no aggression on these occasions, but much vocalisation for a period of ten or twenty minutes. The animal moves on all fours, running rapidly along branches, climbing and jumping, mostly at a few metres above the ground, but descending to the forest floor on occasion.
