The Sunda flying lemur (Galeopterus variegatus ), also known as Sunda colugo, Malayan flying lemur and Malayan colugo, is a colugo species. It is native throughout Southeast Asia ranging from southern Myanmar, Thailand, southern Vietnam, Malaysia to Singapore and Indonesia.
The Sunda flying lemur is not a lemur and does not fly. Instead, it glides as it leaps among trees. It is strictly arboreal, is active at night, and feeds on soft plant parts such as young leaves, shoots, flowers, and fruits. After a 60-day gestation period, a single offspring is carried on the mother's abdomen held by a large skin membrane. It is a forest-dependent species.
The head-body length of Sunda flying lemur is about 33 to 42 cm (13 to 17 in). Its tail length measures 18 to 27 cm (7.1 to 10.6 in), and it weighs 0.9 to 1.3 kg (2.0 to 2.9 lb).
The Sunda flying lemur is protected by national legislation. The Sunda flying lemurs are often hunted by local people with spears or other lethal equipment for various reasons such as food and fur. Habitat loss is known to occur intermittently, particularly in developing countries such as Malaysia. In addition to deforestation and loss of habitat, local subsistence hunting poses a serious threat to this animal. Competition with the plantain squirrel (Callosciurus notatus ) represents another challenge for this species. More information is needed on population declines, but at present, the rate of the decline is not believed to merit listing in any category lower than least concern.

starts withThe Sunda (or Malayan) flying lemur or “colugo” does not belong to the prosimian group like true lemurs, but is in a zoological order of its own, Dermoptera or "skinwings", which has only one genus and two species: the Philippine and Sunda flying lemurs. The latter is mottled grayish or brownish on its upper parts and is paler below. Flying lemurs do not actually fly, but glide from one tree to the next, by means of the patagium, a membrane that stretches from their forelimbs to their tail. There is little information about their life span but the oldest known individual in captivity lived to 17.5 years old.
Sunda flying lemurs inhabit Southeast Asia and Indochina (including Viet Nam, Lao PDR and Cambodia), south through Thailand, eastern Myanmar and Malay Peninsula and surrounding islands to Indonesia (Sumatra, Kalimantan and western Java). They are strictly arboreal, living in the treetops in lowland tropical rainforests. They also live in highlands and adapt readily to plantations and disturbed forests edges.
Sunda flying lemurs live either solitary or in small groups that are loosely connected. They can be territorial as regards foraging and sleeping areas. They are mainly nocturnal. They 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. 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.
Sunda flying lemurs are strict herbivores (folivores and frugivores), eating soft plant parts like fruits, flowers, buds, nectar, sap and young leaves.
Not much is known about the reproduction and mating of Sunda flying lemurs. They will mate at any time of the year. Gestation lasts about 60 days and a single offspring is born, rarely, twins. Young are underdeveloped when born and weigh about 35 g. Until weaned they travel clinging to their mother’s belly, who will also fold her patagium near her tail to provide a soft warm pouch for her baby. Weaning is at six months old, and sexual maturity is reached at around three years. Females can mate again soon after giving birth, and may be pregnant when still nursing.
Despite Sunda flying lemurs being fairly adaptive to a habitat of disturbed forests, they have been decreasing in number due to loss of habitat from logging and the development of farm land. Local subsistence hunting is also a serious threat, as well as competition in plantations with the plantain squirrel.
The IUCN Red List and other sources do not provide the Sunda flying lemur total population size. However, the Encyclopedia of Life resource states that the population density of this species has been estimated for the 2,000 hectares of Singapore’s protected forests at one individual for each two hectares, an estimate of about 1000 individuals. Currently this species is classified as Least Concern (LC), but its numbers today are decreasing.
Sunda flying lemurs eat fruit and flowers and so may have a role in seed dispersal and flower pollination.
