The Sunda flying lemur, Galeopterus variegatus, is also known as the Malayan colugo. Despite its name, it is not a true lemur and it does not truly fly. Instead, it is a gliding mammal from Southeast Asia.
A large skin membrane called a patagium stretches from the neck to the limbs and tail. When the animal leaps from a tree, this membrane opens like a furry kite, allowing it to glide long distances between trunks while losing very little height.
Sunda flying lemurs are nocturnal and almost completely arboreal. They climb well on tree trunks and branches, but they are awkward on the ground, so staying in the canopy helps them feed and avoid danger.
Their diet is mostly plant material, including young leaves, shoots, flowers, fruit, sap, and nectar. Their mottled fur helps them blend against bark during the day while they rest on a tree trunk or branch.
Females usually have a single young that clings to the mother's belly, even during glides. The species is currently considered widespread, but hunting and habitat loss can still affect local populations.
