The Rotnasen- or Rotohrmeerkatze ( Cercopithecus erythrotis ) is a primate of the genus monkeys ( Cercopithecus ) within the family of Cercopithecidae (Cercopithecidae).
The fur of the red-nosed monkey is gray-brown on the upper side, the underside is lighter, more whitish. The bluish face is characterized by a yellow-white whiskers and the eponymous red ears and nose. The animals reach a head trunk length of 40 to 60 centimeters and a weight of 3 to 6.5 kilograms, the males are larger than the females.
These animals are native to a small area in central Africa , more precisely southern and eastern Nigeria , southwestern Cameroon and the island of Bioko, which belongs to Equatorial Guinea . Their habitat are mainly deep forests.
Red-nosed monkeys are diurnal tree-dwellers who mostly live in the lower or middle layers of the trees. They live together in groups of 4 to 35 animals. These consist of a male, several females and their offspring. The diet of these animals consists mainly of fruits, but they also eat insects, leaves and buds.
Little is known about reproduction, but it should be the same as that of other monkeys. After a gestation period of around five to six months, the female usually gives birth to a single young. This is weaned at around six months and sexually mature at two to three years.
Due to urban sprawl and progressive deforestation, the distribution area of the red-nosed monkey is severely fragmented, and there is also the threat of hunting for its meat. The IUCN lists the species as endangered ( vulnerable ).
