The Allen-Galago ( Sciurocheirus alleni , Syn .: Galago alleni ) is a primate species from the Galagos family (Galagonidae). The Cameroon Galago and the Gabon Galago were separated as separate species. Together they form the genus of the squirrel galagos ( Sciurocheirus ).
features
Allen-Galagos, like all Galagos, are relatively small primates. They reach a head body length of 16 to 24 centimeters, plus a tail 20 to 30 centimeters long. The weight is around 200 to 300 grams. Their fur is dark brown or black on the top, the underside is lighter. The head is characterized by clear rings around the large eyes, by the hairless, highly mobile ears and by the narrow, pointed snout. The tail is bushy and longer than the body.
Distribution and way of life
Allen-Galagos are endemic to the island of Bioko, which belongs to Equatorial Guinea . Their habitat is forests, although they prefer secondary forests with dense undergrowth .
They are nocturnal animals that usually retire to sleep in tree hollows or leaf nests during the day. At night they go in search of food, often only staying at a height of 1 to 2 meters. Their jumps in foraging for food are frog-like in that landing is done with their hands, not feet first. They live solitary and have very large roaming areas.
The diet of the Allen Galagos consists mainly of fruits and insects.
After a gestation period of around 130 days, the female usually gives birth to a single young. In its first weeks of life, the mother “parks” the young in the vegetation while they are looking for food and then brings them back to the nest.
threat
These animals are endemic to an island of only around 2000 km², where their habitat is increasingly fragmented and restricted. The IUCN lists the Allen-Galago as "high risk" ( endangered ).
The species is no longer kept in Europe, former owners are Frankfurt, London, Rotterdam and Trinity.
