Primate World Animal Fact Sheet
GEOFFROY'S TUFTED-EAR MARMOSET
Callithrix geoffroyi

Range:
Remnant forests in southeastern Brazil
The marmoset and tamarins are the most diverse of the new world primates. The coats are fine, silky and often colorful. They share several characteristics unusual among other primates. These include small, modified claws instead of nails (except for their big toe), and two as opposed to three molar teeth in either side of the jaw.

Marmosets can be distinguished from tamarins by the length of their lower canine teeth, which are the same length as the incisors. This enables them to gouge holes in tree bark to feed on the gum and sap. Tamarin canines project above the incisors.
