Some 50 to 100 extant species are now placed in this genus by various authors; many other species formerly placed in Rana are now placed elsewhere. Frost [3] restricted Rana to the Old World true frogs and the Eurasian brown and pond frogs of the common frog R. temporaria group, [4] although other authors disagreed with this arrangement.
The bullfrog has been introduced in Hawaii, South America, Asia, the Caribbean, and Europe for various purposes including frog farming and population control of other species. [19] It is very common on the West Coast , especially in California , where it is believed to pose a threat to the California red-legged frog , and is considered to be a ...
The green tree frog is the only species in the hyla genus in the southeastern U.S. that commonly breeds around predatory fish habitats. [21] Some evidence demonstrates that the length of the breeding season is correlated with latitude; seasonal length decreases as latitude increases due to temperature limitations.
Lithobates sylvaticus [1] [2] or Rana sylvatica, [3] commonly known as the wood frog, is a frog species that has a broad distribution over North America, extending from the boreal forest of the north to the southern Appalachians, with several notable disjunct populations including lowland eastern North Carolina.
The name was defined by Hillis and Wilcox (2005) for a subgenus of four Central and South American frogs within the genus Rana. [4] [5] The subgenus was subsequently expanded to seven species in Central and South America in a systematic revision of the genus Rana. [6]
North America has many species of the family Hylidae, including the gray tree frog (Hyla versicolor) and the American green tree frog (H. cinerea). The spring peeper ( Pseudacris crucifer ) is also widespread in the eastern United States and is commonly heard on spring and summer evenings.

The native peoples of South America extract poison from these frogs to apply to their weapons for hunting, [188] although few species are toxic enough to be used for this purpose. At least two non-poisonous frog species in tropical America (Eleutherodactylus gaigei and Lithodytes lineatus) mimic the colouration of dart poison frogs for self ...
