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
Asháninka arboreal chinchilla rat Asháninka arboreal chinchilla rat The Asháninka arboreal chinchilla rat ("Cuscomys ashaninka") is a large species of chinchilla rats from the Andes of far northern Cusco in Peru. It was first scientifically described in 1999. The first specimen of this species was discovered by Dr. Louise Emmons, a researcher of the Smithsonian Institution from Washington, D.C., who found it by chance while climbing in the Vilcabamba Mountains near Machu Picchu. Emmons named the genus after the city of Cusco, and she named the species for the Asháninka people who live in Peru. The animal has grey fur, with a white nose
