The frog's back is dotted with elongated warts, often in undulating longitudinal rows that may be orange along the flanks.

There is only a single genus within the family, and there are more extinct species and genera than currently living in the phylogenetic tree.

These frogs can be found in France, Northeastern Spain and a small part of Northwestern Italy (southern Piedmont and Liguria, specifically).

[6][7] The current situation of the genus is under discussion and there is disagreement regarding the taxonomy due to the separation of the lineages, especially in the different contact zones within the Iberian Peninsula.

Though they can live comfortably in that range, they prefer to breed at lower elevations of around 60–460 meters (200-1,500 feet) above sea level.

[10] They can breed twice a year, once in the autumn and once in the spring, and having two separate mating seasons is of evolutionary benefit as this increases their numbers of offspring.

[11][12][13] In France, the breeding season spans from the end of February to early April; in Portugal, it is from November to March.

[15] Mediterranean species typically prefer autumn reproductions, which may be regulated by air temperature and biological instinct in the frog.

[2] In the metamorphosis process, parsley frogs exhibit phenotype plasticity, in part because their breeding habitats are so uncertain.

[10] In ponds that are shallower or dry more quickly, different phenotypes or characteristics are observed in the young frogs.

Similar trends persist once the tadpoles metamorphose into toadlets, with the drier ponds producing smaller frogs.

[19] The males create a relatively quiet croaking noise with the help of their paired inner vocal sacs, also underwater.

[14] In addition to plasticity, parsley frogs also exhibit a great deal of true genetic diversity.

[6] The mapped microsatellites, or small repeats of DNA, can indicate uniqueness and ability to splice mRNA and other genetic material differently.

[4] There used to be a larger concern for the survival of this species, but in recent years it has been determined that they are at low risk for extinction.

[1] One large issue facing these frogs related to climate change is introducing invasive species, such as fish and crayfish.

[20] The introduction of the American red swamp crayfish, Procambarus clarkii, is an example of how invasive species can impact parsley frog behavior and life.

Native tadpole predators can include larval Aeshnid dragonflies, or other insects or animals they share habitat with.

[20] The invasive fish species, Gumbusia holbrooki (Eastern mosquitofish), first appeared in their habitats near the Iberian peninsula several decades ago.

[1] The biggest threat to their breeding pools is drying,[10] which can be precipitated by man-made drainage of wetlands or construction work in their environments.

[10] The parsley frog has a relatively high ability to adapt and exhibit plasticity (see above breeding and early life behaviors).
