Red-bellied titi

The red-bellied titi or dusky titi (''Callicebus moloch'') is a species of titi, a type of New World monkey, endemic to Brazil. It lives in forests and thickets.
It has a rounded head and a thick, soft coat and frequently adopts a characteristic posture with the body hunched, limbs close together, and a tail hanging down. The body is 28–39 cm long, and the tail is 33–49 cm.
It can move quite fast if necessary but rarely does so and generally stays within a fairly small area, feeding on fruit, insects, spiders, small birds, and bird's eggs. It is diurnal and moves in pairs or family groups, which communicate by means of a wide repertoire of sounds. The female gives birth to a single offspring.

The palm consist of two elongated central pads, a hypothenar pad and a thenar pad.
The skull is orthognathous, orbits are unfenestrated, balls are inflated ventrally, and a large sinus found above the nasal. The foramen magnum is located towards the front, and the atlas has shallow anterior articular facets which allow the condyles to attach. Anterior margin of the lacrimal fossa is formed by or near the maxilla. The premaxilla is short, giving the appearance of a small, not especially prognathic face relative to other platyrrhines.
