Farthest gliding amphibian

Certain species of "flying frogs", such as Wallace's flying frog (Rhacophorus nigropalmatus), are able to glide in excess of 15 metres (50 feet) horizontally during leaps between trees using the extensive webbing on their feet and skin flaps on their bodies to increase air resistance and sustain time in the air. Many scientists prefer to use the name "gliding frogs".

Wallace's flying frog is native to tropical rainforest in south-east Asia, on both the mainland Malay Peninsula and several islands of Indonesia. It is named after the Victorian naturalist Alfred Russel Wallace (1823–1913), who introduced many new species to Western scientists following extensive field trips around Australasia and south-east Asia. This species was one of the first widely documented to display this behaviour.

For a frog to be considered able to glide it must be able to drop at an angle of 45° or less; other frogs also leap between trees with descent angles more steep than that also using webbed feet/skin flaps to slow their fall, but this is considered "parachuting" rather than gliding.

There are approximately 380 known species of flying/gliding frogs from both Asia and the Americas including two groups of true tree frogs: the Hylidae and the Rhacophoridae.
