common fruit bat / Cynopterus brachyotis
like colugos, bats are also mammals. however, they are fully capable of flight. other characteristics include

-Fox-like face, protruding jaw
-Short to non-existent tail
-Normal to large, dark eyes
-Ears are fully enclosed at the base
-Hair varies in thickness; generally short and fuzzy; front part of head, outer parts of limbs and wing membrane are generally bald.
-Skin is brownish with variation in hue and intensity
-Wings are usually dark with spotted patterns
-Teeth are generally 34 in number and do not fully close; the back molars are flat and wide and used for crushing soft fruits
-Long and agile tongue
-Hands have a small claw on the second fingers which are useful in ripping open fruits; this is a distinguishing factor between Fruit and Insectivorous Bats

colugo / Malayan flying lemur- Cynocephalus variegatus
The term is a misnomer as colugos are not lemurs. neither do they fly. rather, they glide using their skin membranes. they have more fur than bats. they make use of their underside membranes to catch wind currents as they travel from tree to tree. this calls for incredible tact, a superior sense of approximation, judgement and availablility of wind currents to take them across distances. the one i saw happened to glide across a packed expressway- to the other far side of the road!
