The Arthroleptidae / ˌ ɑːr θ r oʊ ˈ l ɛ p t ɪ d iː / are a family of frogs found in sub-Saharan Africa.This group includes African treefrogs in the genus Leptopelis along with the terrestrial breeding squeakers Arthroleptis, and several genera restricted to the Guinean forests of central and west Africa, such as the hairy frog (Trichobatrachus).
The features it shares with modern frogs include a forward-sloping ilium, the fusion of the frontal and parietal bones into a single structure known as the frontoparietal, and a lower jaw bone with no teeth. [11] Czatkobatrachus is another proto-frog with some characteristics similar to Triadobatrachus. It is from the early Triassic in Poland ...
Polypedates maculatus, the Indian tree frog, [1] or Chunam tree frog, is a common species of tree frog found in South Asia. It was described by John Edward Gray in 1830. [2] Although now considered as a separate species again, for a time, the Himalayan tree frog was considered as a subspecies of the Indian tree frog (as P. m. himalayensis). [1]
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca

The synapomorphies that define Pipoidea are the absence of mentomeckelian bones, absence of lateral alae of the parasphenoid, fusion of the frontoparietals into an azygous element, greatly enlarged otic capsules, and a tadpole with paired spiracles and which lacks beaks and denticles.
Rana (derived from Latin rana, meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs.Members of this genus are found through much of Eurasia and western North America.
The hairy frog is also notable in possessing retractable "claws", which it may project through the skin, apparently by intentionally breaking the bones of the toe. [5] These are not true claws, as they are made of bone, not keratin. In addition, there is a small bony nodule nestled in the tissue just beyond the frog's fingertip.
