Saimiri, commonly known as squirrel monkeys, are small primates native to the tropical rainforests of Central and South America. They have distinctive short, greyish fur with a white face mask and a bright yellow-orange underside. Highly social, they live in large troops and are known for their agility and playful behavior. Squirrel monkeys have a diet primarily consisting of fruits and insects, playing a crucial role in seed dispersal and pest control within their ecosystem.

Saimiri, commonly known as squirrel monkeys, are native to the tropical forests of Central and South America. Their geographical distribution includes countries such as Brazil, Colombia, Ecuador, Peru, and Bolivia, with subspecies variations extending into regions of Costa Rica and Panama.

Squirrel monkeys typically inhabit a variety of forest types, including rainforests, riverine forests, and occasionally mangroves. They are most commonly found in the canopy layer of these forests, which provides dense foliage for shelter and abundant food resources.

Squirrel monkeys occupy an ecological niche as arboreal omnivores. They are highly adapted to life in the trees, using their agile limbs and prehensile tails to navigate the canopy. Their diet primarily consists of fruits, insects, and small vertebrates, playing a crucial role in seed dispersal and pest control within their ecosystem.
