The marmoset is a small primate belonging to the family Callitrichidae, primarily found in the forests of South America. These social animals are known for their distinctive features, including a small size, long tails, and expressive faces. Marmosets typically live in family groups and communicate through a variety of vocalizations. Marmosets are omnivorous, feeding on fruits, insects, and small animals. They play a crucial role in their ecosystem by helping to disperse seeds. Due to habitat loss and the pet trade, some marmoset species are threatened, making conservation efforts important for their survival in the wild.
