Family Ranidae
True Frogs
By Dana Greenwald
The Ranidae family consists of typical frogs with long legs, narrow waists, smooth skin, free fingers, and toes joined by webs. Most have dorsolateral ridges, which are raised longitudinal folds of glandular tissue. Vocal pouches on males are situated either at the sides or underneath of the throat. Breeding males have swollen forearms and enlarged thumbs. This family can be found in all continents except Antarctica. The only genus found in North America is Rana.
