Historical reference: Do not rely on this information. It is very old. About this collection
Tree-Frog, any individual of the amphibian family Hylidae, widely distributed, and modified for arboreal life. On the last joint of each toe is a sucker, and these enable the frogs to cling to the smooth surfaces of leaves. The common Tree-Frog (H. arborea) is found in Europe, though not in Britain. It is bright-green in colour, and smaller than the common Frog.
