The European tree frog (Hyla arborea) is a small frog that can grow 5 centimeters in size at most. It is the only member of the wide-spread tropical tree frog family that's indigenous to Mainland Europe. Characteristic are the discs on the frog's feet which it uses to climb trees and hedges. The European tree frog also has a stripe on its flank that reaches from its nostrils to it's backside.
Historically, tree frogs were used as barometers because they'd respond to approaching rain by quacking.
Appearance
Both males and females animals reach sizes up to 45 millimeters, sometimes even 50, though that's rare. The smooth, shining, usually leaf-green top side and the white-yellowish to grey lower surface are separate by a black line against the green, which forms a loop at the hips. The head is rounded, the lip drops strongly, the pupil is horizontally elliptically and the eardrum clearly recognizable.
