Arboreal locomotion a method known as parachuting, such as "Rhacophorus" (a "flying frog" species) that has adapted toe membranes allowing it to fall more slowly after leaping from trees. Many species of snake are highly arboreal, and some have evolved specialized musculature for this habitat. While moving in arboreal habitats, snakes move slowly along bare branches using a specialized form of concertina locomotion, but when secondary branches emerge from the branch being moved on, snakes use lateral undulation, a much faster mode. As a result, snakes perform best on small perches in cluttered environments, while limbed organisms seem to do best on
Animals in Buddhism not expressly commanded in the Pāli canon, it is evidently viewed as an ideal state from which human beings have fallen; the Aggañña Sutta (DN.27) explains how human beings, originally sustained on various kinds of vegetable matter (compare Gen.1:29-30), as the result of increasing wickedness began to live by hunting, which was originally thought of as a demeaning occupation.
