Frog populations have declined dramatically since the 1950s. More than one-third of frog species are considered to be threatened with extinction, and more than 120 species are believed to have become extinct since the 1980s. [202] Among these species are the gastric-brooding frogs of Australia and the golden toad of Costa Rica.

The hairy frog (Trichobatrachus robustus) also known as the horror frog or Wolverine frog, is a Central African species of frog in the family Arthroleptidae.It is typically considered monotypic within the genus Trichobatrachus, [2] but based on its genetics, it should be included in Astylosternus instead.

When feasible, this species utilizes caves for thermal refugia during the coldest months of the year. [8] The pickerel frog is a trogloxene species, meaning they occur in caves, but are unable to complete their life cycles there. Though they are most abundant in caves during the winter, they are active deep within caves at almost any time of year.
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 American green tree frog (Dryophytes cinereus or Hyla cinerea) is a common arboreal species of New World tree frog belonging to the family Hylidae. This nocturnal insectivore is moderately sized and has a bright green to reddish-brown coloration. [ 2 ]
The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage.
The species is very similar in appearance to another in the area – B hermogenesi – which also has the same yellowish-brown skin, lives in leaf litter, and emerges as tiny frogs from their eggs ...
