Tamarins are a group of small, tree-dwelling primates found in Central and South America. There are several synonyms for the word 'tamarin', including 'marmoset', 'monkey', 'squirrel monkey', and 'titi'. These primates are known for their small size, long tails, and distinctive manes or crests of hair on their heads. They are highly active and sociable animals, living in social groups that can consist of up to 15 individuals. Tamarins have a varied diet of fruits, insects, and small vertebrates, and they play an important role in the ecosystems in which they live. Despite their small size, tamarins are a keystone species in their habitats, helping to maintain the health and diversity of the plant and animal communities around them.
