Color Blindness in Lemurs

Lemurs are a group of small primates found only on the small island of Madagascar. Due to Madagascar’s highly variable climate lemur evolution has produced a wide range of species, remarkable for such a small geographic area. Studies into Lemur’s visual system has revealed what colors these creatures can, and cannot see.

Can Ruffed Lemurs

See Red?

Ruffed lemurs are usually colorblind—all males are—but some females can see something the others can’t: the color red. But how do you ask a lemur to tell you what they see? Learn about Raymond Vagell’s color vision research at Duke Lemur Center. He asks lemurs to show him whether they can see red using a touchscreen.

The Duke Lemur Center in Durham, North Carolina (USA) has the largest collection of captive lemurs outside of Madagascar. Its mission is to advance lemur science and conservation, and is also open to the public for guided tours.
