Although colugos are sometimes referred to as flying lemurs, they are not true lemurs.

Found gliding through the trees in southeast Asia, colugos are the best adapted mammals in the world for flight, aside from bats. For a time they were considered to be a close living relative of bats, though they have since been reassigned to a lineage closer to primates.

They can remain airborne for a distance of at least 70 meters without losing much height, an impressive feat since they can grow to the size of a possum.
