What is a "marmoset"?

Marmosets are small primates known for their tiny size, typically weighing less than a pound, and their distinct appearance with tufted ears, long tails, and often brightly colored fur. They have specialized claws for climbing trees and are highly agile, acrobatic creatures. Marmosets are highly social animals that live in family groups and communicate through vocalizations, gestures, and scent marking. They are known for their high-pitched calls and energetic, playful behavior. Marmosets are primarily insectivorous, feeding on insects, tree sap, and small vertebrates. They are found in the tropical rainforests of South America and are considered as part of the New World monkey family, Callitrichidae.
