In the free-roaming horse, it hardens into a callus consistency with a near-smooth surface. [citation needed] For good health, the horse requires dry areas to stand. If chronically exposed to bacteria, for example standing in manure, the frog will develop an infection called thrush. [2] The frog is anatomically analogous to the human fingertip. [3]
The marsupial frogs are a disputed family (Amphignathodontidae) in the order Anura. [1] When treated as a separate family, it consists of two genera, Gastrotheca and Flectonotus. [2]

The amount of entrained water the frog can ingest is related to its ability to actively increase its body volume. The frog's buccopharyngeal cavity (the cavity connecting the mouth and the pharynx) is very distensible and can expand substantially. It uses its entire trunk to rapidly enlarge the cavity, which expands into the lower end of the trunk.
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
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 (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. [ 3 ]
Triadobatrachus is an extinct genus of salientian frog-like amphibians, including only one known species, Triadobatrachus massinoti. It is the oldest member of the frog lineage known, and an excellent example of a transitional fossil. It lived during the Early Triassic about 250 million years ago, in what is now Madagascar.
