Colugos are arboreal gliding mammals found in Southeast Asia. Just two extant species make up the entire familyCynocephalidae and orderDermoptera. They are the most capable gliders of all gliding mammals, using flaps of extra skin between their legs to glide from higher to lower locations. They are also known as cobegos or flying lemurs, although they are not true lemurs.
