The Coimbra spring monkey ( Callicebus coimbrai ) is a primate species from the subfamily of the spring monkeys within the sakia monkey family (Pitheciidae). It is named in honor of the Brazilian zoologist Adelmar Faria Coimbra-Filho and was described in 1999 .
features
Coimbra's jumper monkeys, like all jumper monkeys, are relatively small primates with thick fur and a long, bushy tail that cannot be used as a prehensile tail. Their fur is colored gray or yellow-gray, on the back there are some suggested dark horizontal stripes. The hands and feet are black, the tail is colored bright orange. The head is small and rounded, and there is a black horizontal stripe on the forehead that merges into the tufts of the ears, which are also black.
distribution and habitat
Coimbra's jugular monkeys live in southeastern Brazil , their range includes the coastline of Sergipe and the northeast of Bahia . Forests are their habitat.
Way of life
Little is known about the way of life of the Coimbra ape monkeys, presumably it corresponds to that of the other apes. Jumper monkeys are diurnal and mostly stay in the trees. They move either on four feet or by jumping. They live in family groups, the two partners often stay together for life. These groups inhabit a fixed territory that is communicated to other animals through morning duet chants. Their diet consists mainly of fruits, to a lesser extent they also eat leaves and sometimes insects. The fathers take an intensive part in raising the young, they carry the child and give it to the mother only to suckle.
Danger
The Atlantic coastal forests of Brazil have been largely destroyed by conversion into agricultural areas or settlement areas, which has reduced and fragmented the range of the Coimbra monkey. Today it covers a total of around 150 km², the total population is estimated at around 500 to 1000 animals. The IUCN lists the species as "critically endangered" ( endangered ).
