Flying frog

Flying frog

The "flying" frog is a frog that has the ability to glide. That is, it can descend at an angle of less than 45° relative to the horizontal. Arboreal frogs (non-flying frogs) can also descend vertically, but only at angles greater than 45°, which is referred to as parachutingEmerson, S.B., Travis, J., & Koehl, M.A.R. (1990). "Functional complexes and additivity in performance: A test case with 'flying' frogs." "Evolution", 44(8), 2153-2157.] . Flying frogs have evolved independently among 3,400 species of frogs Emerson, S.B., & Koehl, M.A.R. (1990). "The interaction of behavioral and morphological change in the evolution of a novel locomotor type: 'Flying' frogs." "Evolution", 44(8), 1931-1946.] from both New World ("Hyla") and Old World ("Rhacophoridae") families and their evolution is seen as an adaptation to their life in trees, high above the ground. Characteristics of the Old World species include "enlarged hands and feet, full webbing between all fingers and toes, lateral skin flaps on the arms and legs, and reduced weight per snout-vent length". These morphological changes contribute to the flying frog's aerodynamic abilities. Alfred Russel Wallace made one of the earliest reports of the flying frog, from observations in the Indo-Malayan region [Oliver, J.A. (1951). "'Gliding' in amphibians and reptiles, with a remark on an arboreal adaptation in the lizard, anolis carolinensis carolinesis voigt." "The American Naturalist", 85(822), 171-176.] . The species he observed was later termed Wallace's Flying Frog ("Rhacophorus nigropalmatus").They have suction pads on their webbed feet which helps their balance in the high trees that they live in.

It is also possible to make frogs fly (more accurately, to levitate) by placing them in a magnetic field (see diamagnetic levitation).
