Colugos, flying lemurs, or cobegos, are arboreal gliding primatomorphs that are native to Southeast Asia. Their evolutionary closest relatives are primates. There are just two living species of colugos: the Sunda flying lemur and the Philippine flying lemur. These two species make up the entire family Cynocephalidae and order Dermoptera, from Ancient Greek δέρμα (dérma), meaning "skin", and πτερόν (pterón), meaning "wing".
