Squirrel monkeys are small primates native to the tropical forests of Central and South America. They belong to the family Cebidae and are known for their distinctive yellow-orange fur and long tails, which help them balance as they move through the trees. Adult squirrel monkeys typically weigh between 15 to 20 ounces and have a body length of about 16 to 24 inches. These monkeys are highly social animals, often living in groups of 10 to 30 individuals. They are known for their playful behavior and vocalizations, which include a variety of chirps and whistles. Squirrel monkeys primarily eat fruits, insects, and small animals, making them important for seed dispersal in their ecosystems.
