The characteristics of anuran adults include: ... In 2008, Gerobatrachus hottoni, a temnospondyl with many frog- and salamander-like characteristics, ...
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).
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. However, all archaeobatrachians have free vertebrae, whereas ...
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 .
New Jersey has 16 species of frogs and toads, 13 of which can and have been sighted in North Jersey. ... The first way to tell them apart is by their physical characteristics including skin ...
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 ...
Anurans all share a number of morphological characteristics, so researchers have had to use DNA testing to understand their relationships. ML and Bayesian analyses using a nuclear marker toolkit have resolved some of the relations of the anurans in Hyloidea. 53 out of the 55 previously established nodes on the phylogenetic tree were supported by this DNA testing.

A Cuban tree frog explored in Lake Worth, Florida in 2010. According to the University of Florida, the frogs are an invasive species.
