Sakis occur in a wide variety of habitats from lowland tropical rainforests to montane forests (Mittermeier 1977; Norconk et al. 2003; Defler 2004). They have been recorded in drier forests, palm patches, pina swamp forest, and secondary and fragmented forests.

Sakis are medium-sized primates (1-3 kg). They are specialised morphologically for seed predation. The diet is made up of seeds, fruit pulp, young leaves, insects and flowers. Members of this genus form small, cohesive groups (2-9 individuals), generally comprising a single male-female breeding pair and several young. Day ranges (1.5-2 km) and home ranges are small (10-25 km), and sakis exhibit behaviours associated with territory defence (Norconk 2007).

Unknown

There are no obvious major threats to the species at present, although they are subject to localized hunting and habitat loss. They are certainly hunted in Bolivia (Tarifa 1996), where they have a restricted range in the north-west of the country.

Present in Parque Nacional de Amazônia and the following Amerindian Reserves: Andira Marau, Coatá Laranjal, Ipixuna, 9 de Janeiro and Deni.
It is listed on CITES Appendix II.
