The green frog is a frog three to five inches long, found in eastern North America, variable in color, but having in general the head and shoulders of brilliant green, shading to a dull olive. The green frog,
Rana clamitans is distinguished from the bullfrog, which it otherwise resembles, by folds of skin along its sides. It hibernates in mud and moss, and molls three or four times a year. The eggs, laid during April, form jelly-like masses on twigs just beneath the water surface, and at first develop rapidly; the tadpole stage, however, may last for two years. The peculiar shrill cry of the young green frog gave rise to the old name, "screaming frog."
