Physical description
This medium-sized monkey is distinguished by its marked sexual dimorphism. The male displays thick black fur and a contrasting white face that gives it a unique and recognizable appearance. The female, on the other hand, has uniform grayish-brown fur with a more discreet face, often spotted or marked with dark shades. Their long and bushy tail is not prehensile, but it serves them to balance during their arboreal movements.
Size and weight
The White-faced Saki measures approximately 30 to 40 cm in length, with a tail of similar size, and weighs between 1.5 and 2 kg.
Habitat and distribution
It is found in the humid tropical forests of South America, particularly in Brazil, Venezuela, Colombia and the Guianas. It is particularly at ease in the canopy, where it moves by jumping from tree to tree with agility.
Diet
The White-faced Saki is mainly frugivorous, but also consumes seeds, flowers, insects and sometimes small vertebrates. Its varied diet and powerful jaw allow it to feed on hard-shelled fruits, which are inaccessible to other species.
