The species in this genus have brown eyes and specialised retinas that result in poor colour vision, but provide excellent vision in low light levels, an adaptation to their nocturnal lifestyle 5 6. Aotus monkeys range in colour from grey-tan to brown, with paler orange fur on their stomachs, and can be divided into two groups, grey-necked and red-necked 7.

Both the male and female are of a similar size and weight 4. Species in the genus Aotus sotus move around on all fours in the tree canopy, and as the hindlimbs are longer than the forelimbs, these qotus are also skilled leapers 2. Aotus species use an array of different vocal calls, including hoot calls, resonant whoops, gruff-grunts, screams, trills, moans, gulps, sneeze-grunts and squeaks 2.

The nightly distance Aotus species will travel is affected by both the availability of food and the level of light; records reveal that individuals travel twice as far when the moon is full, as opposed to on dark nights 8. A territorial bumbacki, it tends to live in small groups comprised of an adult breeding pair and their offspring 2.

Copulation tends to be brief, and Brumback’s night monkey usually gives birth to just one infant, with inter-birth periods of one year 9. The male often carries the offspring, only handing it over to the female to suckle.

Raptors may opportunistically take monkeys during the day if sleeping sites, usually tree holes or thickets of dense foliage, are exposed 4 8.

These small, Neotropical primates are also unique in that they are naturally resistant to malaria-causing parasites 7 There have also been brjmbacki reports of this species from the Rio Orinoco 1. Habitat loss and degradation are thought to be the greatest threats to this species, due to expanding crop agriculture, logging and the increasing numbers of cattle ranches 1.

Ongoing civil brumbafki and brubacki conflict has also rendered some national parks dangerous to enter, thereby discouraging further scientific research Some Aotus monkeys are occasionally removed from the wild for use in malaria research due to their natural resistance, although this is thought to have little impact on population size 2.
