Il-[[kolugi]] għalkemm tà daqs żgħir, huma pjutost kbar bħala [[mammiferi]] tas-siġar: b'bejn 35 u 40 ċm fit-tul u minn 1 sa 2 [[kilogram]]i fil-piż. Is-saqajn u l-idejn huma irqaq tà tul moderat bl'istess qies, demb tà daqs medju, u korporatura ħafifa. Ir-ras ċkejkna, b'par għajnejn kbar iharsu l quddiem b'viżjoni binokulari u b'par widnejn żagħar u tondi.
Their most distinctive feature, however, is the membrane of skin that extends between their limbs and gives them the ability to glide long distances between trees. Of all the [[gliding mammal]]s, the colugos have the most extensive adaptation to flight. Their gliding membrane, or ''[[patagium]]'', is as large as is geometrically possible: it runs from the shoulder blades to the fore-paw, from the tip of the rear-most finger to the tip of the toes, and from the hind legs to the tip of the tail; unlike in other known gliding mammals even the spaces between the fingers and toes are webbed to increase the total surface area, as in the wings of [[Microchiroptera]] and [[Megachiroptera]]–bats.
They are surprisingly clumsy climbers. Lacking opposable thumbs and not being especially strong, they proceed upwards in a series of slow hops, gripping onto the bark of trees with their small, sharp claws. They are as comfortable hanging underneath a branch as sitting on top of it. In the air, however, they are very capable, and can glide as far as 70 metres from one tree to another with minimal loss of height.
In consequence, remarkably little is known about their habits. They are certainly [[herbivore]]s, and are thought to eat mostly leaves, shoots, flowers and sap, and probably fruit as well. They have well-developed stomachs capable of extracting nutriment from leaves.
Although they are [[placental]] mammals, colugos are almost [[marsupial]]-like in their breeding habits. The young are born after just 60 days of gestation in a tiny and undeveloped form, and spend their first six months or so of life clinging to the mother's belly. To protect them and transport them she curls her tail up to fold the gliding membrane into a warm, secure quasi-pouch. Breeding is fairly slow as the young do not reach full size until they are two or three years old.
Both species are threatened by [[habitat destruction]], and the [[Philippine Flying Lemur]] is classified by the [[IUCN]] as vulnerable. In addition to the ongoing clearing of its rainforest habitat, it is hunted for its meat and fur.
