Gliding Lemurs (Cynocephalus Variegatus) are largely nocturnal by nature because of their aerial acrobatics in daylight would present predators with too easy a target.
Flying lemurs, of course don’t fly, but can glide up to 130 true the forest in shallow dive.
They do this by climbing a tree in a rather awkward fashion, encumbered as they are by folds in their gliding membrane.
Om reaching a suitable tree height, they glide gradually down to a lower level on another tree.
They then must begin the laborious climb up all over again.
This gliding is especially impressive for female flying lemurs as they carry their single young attached to their bellies when in flight.
