A sap-tapping tool

Marmosets belong to the family Callitrichidae (New World monkeys), which also includes tamarins. A difference between marmosets and tamarins is that the incisors in a marmoset’s lower jaw are as long as its canine teeth. This allows them to scrape holes in the tree bark in order to get at their favourite food: tasty tree sap!

Did you know?

Silvery marmosets drive away intruders with loud cries and
fierce faces. A stern frown and pursed lips can mean only
one thing: Get lost!
