True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia.
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.
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.
[4] [5] The subgenus was subsequently expanded to seven species in Central and South America in a systematic revision of the genus Rana. [6] The name was previously used by Frost et al. as a separate genus of ranid frogs that included most of the North American frogs traditionally included in the genus Rana , [ 7 ] including the American ...
One study finds that there are at least 31 tree frog species of the genus Hyla (or Dryophytes) in North America, Central America, and Eurasia. Examples include both the H. gratiosa and H. walkeri . While many tree frogs reside in the New World , a notable number of frogs inhabit the Eurasian continent and display unique biogeographic patterns ...
P. ocularis is the smallest frog in North America, only reaching a maximum head-body length of 19 mm (0.75 in). It is normally pale brown, but can have a green or pink tinge. This species is further characterized by a variable dark stripe which runs through each of the frog's eyes and down the sides of its body.
