Appearance

Their legs can be yellow or have a reddish tint. Their stomachs will have a yellow tint. The black fur above their eyes forms a shallow arch and is lower on their foreheads than other species.

Black squirrel monkeys tend to be 27 to 32 centimeters in length not among them the length of their tails. Their full length, among them their tails, can be about 40 centimeters longer than their length without their tails.

Range and habitat

The várzea forest of this specific area experiences a consistent cycle of flooding. The patterns of rain can cause a typical buildup of around 35 feet of flooding in the forest. Atypical flooding due to excessive floods over a longer amount of time can threaten black squirrel monkeys' habitat.

Its entire range is within the Mamirauá Sustainable Development Reserve. It resides in the reserve with two other Saimiri species.

Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.

Breeding

Breeding season falls between the months of September and November.

In crisis

Its small size makes it an easy target for its predators. Even so, it may resist predators when it travels in large troops.

CITES lists this taxon on Appendix II. Confirm the current appendix on the CITES checklist.
