Brumback’s night monkey[1] is a nocturnal monkey species found in Colombia.
- Traditionally, it has been considered a subspecies of the grey-bellied night monkey (Aotus lemurinus).
- Still, recently, it has been argued that it should be considered a separate species.
- Like other members of its genus, this species is nocturnal. Its small round head is striped with black and dominated by two large brown eyes.
- The overall effect is not unlike an owl’s; the monkey’s eyes glow a reddish-orange in the reflected light.
- The white eyebrows are bushy, with a patch of darker coat between them. Its gray fur is described as thick and shaggy, and the animal’s underside is reddish brown.
- Its black-brown to orange tail is non-prehensile and invariably has a black tip. The Brumback’s night monkey has slender limbs with long, delicate fingers.
