Read full entry


Average body length for males about 74 mm and for females 83 mm. Shape typical of a green waterfrog, but with less distinct dorsolateral folds than in Rana ridibunda. Eyes closely set, long hind legs and vocal sacs at the corners of the mouth. In most frogs the back is uniformly green, often with a light green longitudinal middorsal stripe. Irregularly shaped dark green spots are randomly distributed over the back. In the loin area the flanks are yellowish. Dark transverse bands on the thighs continue onto the white underside. Vocal sacs of males are usually olive but turn dark gray to black in mating season (Noellert and Noellert 1992).
