Macaco-de-cheiro

<em>Saimiri collinsi</em>, commonly known as Collins' Squirrel Monkey, is a primate species belonging to the genus <em>Saimiri</em> within the family Cebidae. Squirrel monkeys are small, highly social New World primates known for their agility in forest canopies and their complex group dynamics. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are not currently considered at high risk of decline, though ongoing deforestation and habitat fragmentation in Amazonian regions may affect future population stability. Collins' Squirrel Monkey inhabits diverse terrestrial and aquatic-adjacent environments typical of tropical forest ecosystems in South America. Specific country-level distributional records are not detailed in current documentation. Dietary information specific to this species has not been recorded, though squirrel monkeys in general are omnivorous, consuming insects, small vertebrates, fruits, and other plant material. Biological traits of this species remain poorly documented in the scientific literature. Research into the taxonomy and ecology of <em>Saimiri collinsi</em> continues to refine understanding of squirrel monkey diversity.
