The Satéré marmoset[1] (Mico saterei) is native to Brazil, and its genus is characterized by claw-like nails rather than the flat nails of other primates, long lower incisors, a specialized caecum, and squirrel-like movements in trees.
- Satéré marmoset has a bare face, orange-brown abdomen, and dark reddish-brown fur on its back and limbs.
- Its most distinctive feature is its bright orange genitalia. In addition, both males and females have long, fleshy, lip-like appendages that frame the usual sex organs.
- It’s a really odd adaptation, says primatologist Russell Mittermeier, president of Conservation International. We have no idea what its function might be.
