Rana (genus)

Rana (genus)

Rana is a genus of frogs. Species include such archetypal pond frogs as the common frog of Europe, brown frogs, and the New and Old World true frogs, including the various species of leopard frogs and the American bullfrog. Members of this genus are found through much of Eurasia, North America, Africa, Central America, and the northern half of South America. Many other genera were formerly included here; see below for details.

These true frogs are usually largish species characterized by their slim waists and wrinkled skin; many have thin ridges running along their backs but they generally lack "warts" like in typical toads. They are excellent jumpers due to their long slender legs. The typical webbing found on their hind feet allows for easy movement through water. Coloration is mostly greens and browns above, with darker and yellowish spots.
