Adult frogs live in fresh water and on dry land; some species are adapted for living underground or in trees. Frogs typically lay their eggs in the water. The eggs hatch into aquatic larvae called tadpoles that have tails and internal gills. They have highly specialised rasping mouth parts suitable for herbivorous, omnivorous or planktivorous ...
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 numbers of species cited above follows Frost and the total number of known (living) amphibian species as of March 31, 2019, is exactly 8,000, [12] of which nearly 90% are frogs. [ 13 ] With the phylogenetic classification, the taxon Labyrinthodontia has been discarded as it is a polyparaphyletic group without unique defining features apart ...
The family the moor frog belongs to, Ranidae, is a broad group containing 605 species. The family contains ranoid frogs that do not belong to any other families and are found on every continent but Antarctica. [4] The moor frog belongs to genus Rana, which includes species found in Europe and Asia. The moor frog is not found in the Americas ...
The archaeobatrachians are the most primitive of frogs. These frogs have morphological characteristics which are found mostly in extinct frogs, and are absent in most of the modern frog species. Most of these characteristics are not common between all the families of Archaeobatrachia, or are not absent from all the modern species of frogs.
Pig frogs (Lithobates grylio) are a species of frog that belong to the class Amphibia, the order Anura, the family Ranidae, and the genus Lithobates.They are part of the phylum Chordata, which includes animals with a notochord and a hollow nerve cord.

Telmatobius culeus, commonly known as the Titicaca water frog or Lake Titicaca frog, [1] is a medium-large to very large and endangered species of frog in the family Telmatobiidae. [3] It is entirely aquatic and found only in the Lake Titicaca basin, including rivers that flow into it and smaller connected lakes like Arapa , Lagunillas and ...
