A wastebasket amphibian genus containing tree frogs that do not fit anywhere else

Unlike their name suggests, Not all members of this genus live in trees. Previously containing more than 300 species found across Europe, Asia, Africa, and the Americas, a significant revision decreased the number of species in this genus to merely seventeen.

Although tree frogs range in size, most species are small because they rely on leaves and slender branches to hold their weight. Particular adaptations like toe pads and long legs aid the arboreal tree frogs in climbing and jumping. In contrast, the primarily non-arboreal tree frogs find shelter in lakes and ponds or among moist ground cover.
