The equatorial saki ( Pithecia aequatorialis ) is a primate species from the New World monkey group . The species was not described until 1987 , before the stocks were assigned to the monk monkey .
features
Equatorial sakis are medium-sized primates. They reach a head body length of 39 to 44 centimeters, the tail is up to 47 centimeters long. The weight is 2 to 2.5 kilograms. The fur of these primates is long and shaggy, it is predominantly colored with mottled gray, the belly is yellowish or reddish. The tail is very long and bushy, it cannot be used as a prehensile tail. The two sexes differ in the hair on the head: in the males the hair on the top of the head is short and bristle-like, in the females it is long and hangs down and partially covers the face and ears.
distribution and habitat
Equatorial sakis are native to the Loreto region in northern Peru . The northern border of the distribution area forms the lower reaches of the Río Napo , the southern border of the Amazon and the Río Tigre . Their habitat are tropical rainforests .
Way of life
Not much is known about the way of life of the Equatorial Sakis. Like all Sakis they are diurnal tree dwellers and probably live in small groups. These are made up of a monogamous couple and their offspring and live in a fixed territory. Their diet consists mainly of seeds and hard-skinned fruits, to a small extent they also eat other parts of plants and possibly insects.
Danger
Although these primates suffer from habitat destruction and hunting in some places, overall the species is not endangered according to the IUCN ( least concern ).
The species is no longer kept in Europe, the only holder was from 1973 and 1981, Cologne.
