The Common Marmoset (Callithrix jacchus) has very versatile claws which allow them to run vertically up trees, across small branches and leap between trees.
They use their claws and teeth to gouge holes in tree trunks to release the sap/gum that they then eat.
In the wild there are usually 10-12 Marmoset in a troupe, however, only one pair will breed.
The males and older siblings carry the very young.
They use their scent glands to mark objects, which communicates their social and reproductive status to other Marmosets.
