Key adaptations
Marmosets have tegulaes - claw-like nails - on most of their fingers to help them hang on to trees vertically and leap between, and run across, branches.
Social organisation and mating system
Small troops of up to 12 individuals
Polyandrous mating system. Cooperative breeders, only one female in the group breeds at a time while the other help to look after her offspring. This is essential as Marmosets normally give birth to twins. Although, in order for both to survive, offspring need multiple 'fathers' help as they are too heavy for the mother alone to carry.
Did you know that...?
They are among the smallest of all primates and have aboreal locomation similar to squirrels
