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 1.5 to 2.5 pounds 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 communicate using a variety of vocalizations and are primarily diurnal, meaning they are active during the day. Squirrel monkeys primarily eat fruits, insects, and small animals, making them omnivorous.
