Flying lemurs, Langkawi island, Malaysia.
Sunda flying lemurs are not lemurs and they cannot fly. They are related to monkeys, and glide between trees in tropical forests in S E Asia. They can glide more than 100 m with minimal loss in elevation. When threatened, they either climb higher up or remain motionless. These animals are quite helpless if on the forest floor.They live either solitary or in small groups that are loosely connected. They can be territorial in foraging and sleeping areas. They are mainly nocturnal and are strictly arboreal and in the daytime, they sleep high within dense foliage in the treetops or in holes in trees. With all four of their feet, they cling on to the trunk of a tree or the underside of branches. Climbing involves stretching out their two front legs and then bringing up their two back legs, which results in an awkward hopping.
