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
Homosexual behavior in animals Homosexual behavior in animals Homosexual behavior in animals is sexual behavior among non-human species that is interpreted as homosexual or bisexual. This may include same-sex sexual activity, courtship, affection, pair bonding, and parenting among same-sex animal pairs. Research indicates that various forms of this are found in every major geographic region and every major animal group. The sexual behavior of non-human animals takes many different forms, even within the same species, though homosexual behavior is best known from social species. Scientists perceive homosexual behavior in animals to different degrees. The motivations for and implications of these behaviors have yet to
