The family of the world’s smallest primate just got a little bigger. U.S. and Malagasy primatologists have discovered a new species of mouse lemur, an arboreal, fist-size animal on the African island of Madagascar, the home of all lemurs.
The researchers also announced a second new lemur species, one of a group called giant mouse lemurs. The findings bring the total number of known lemur species from 47 to 49.
