This type of monkey can leap farther than most due to it having longer arms than legs.

An exception to this if the male breeding partner is no longer present for any reason (usually only caused by death), then the offspring may stay with its birth group for only twelve weeks to the normal departure age.

For this species, copulation attempts tend to be short and quick, starting with the male and female approaching one another.

To startle a potential predator the night monkey will “scream,” emitting a high pitched shriek.

They will also urinate on their hands and then rub it on different surfaces to show sexual attraction.

A rejection bite is used as tactile communication between mother and offspring after suckling or after around one week old when contact is not welcome.
