Parsley Frog Facts

Physical traits

Parsley frogs (named for his or her speckled inexperienced coloration), are small and gracile, with massive, bulging eyes. They are distinguished from all different frogs by a singular set of morphological options that features the presence of a parahyoid bone, fused Vertebrae I and II, fused astragalus and calcaneum, and three tarsalia bones within the foot. The common physique dimension is 1.57-1.97 in (40-50 mm).

Evolution and systematics

Fossil Pelodytidae (genus Miopelodytes) are identified from the Middle Miocene of Nevada within the United States, and the Eocene of Germany (genus Propelodytes). The designation Pelodytidae mostly contains the fossil varieties, and is characterised by the fusion of the “ankle bones” (astragalus and calcaneum). Fossils of Miopelodytes and the extinct Propelodytes arevacus have a fused astragalus and calcaneum, however different Propelodytes don't. Therefore, the standing of Propelodytes as a pelodytid is questionable. No subfamilies are acknowledged.


The three species have a discontinuous distribution in Europe and western Asia. One species is within the northwestern Caucasus and western Trans-Caucasus, Russia, Georgia, and Turkey. The second is in southern Portugal and southern Spain, and the third is in Belgium, by France to japanese Spain and northwestern Italy.


Parsley frogs are recurrently present in deciduous and coniferous forested canyons, valleys drained by streams, and coastal zones. They may be present in or close to shallow ponds, streams, and flooded quarries. One species appears favor small streams with stony areas and/or sandy bottoms. Larval pelodytids are recurrently present in brackish waters. These frogs may be discovered so far as 900 ft (275 m) away from the closest water supply.


Pelodytids are typically nocturnal. During the day, they retreat to refugia beneath rocks or conceal amongst vegetation on the base of huge rocks or stone partitions. At night time, they forage close to water sources. Parsley frogs hibernate from September to March, relying on the altitude and climate circumstances.

Feeding ecology and eating regimen

Parsley frogs typically forage at night time. Their eating regimen consists primarily of invertebrates, together with flies, crickets, slugs, and worms.

Reproductive biology

Breeding in these frogs happens in the course of the spring and summer season, with a second breeding season doable within the fall. Mating and egg laying appears to be triggered by rainfall. During the breeding season, males emit a low-volume acoustic sign, and apparently could name from beneath water. Amplexus (mating) is inguinal. Although the species are typically terrestrial, they breed in slow-moving to nonetheless waters, with eggs and tadpoles usually present in waters with excessive oxygen content material and low plant vitamins. In France, a number of populations of pelodytid tadpoles have been discovered inhabiting brackish waters. The tadpoles have denticles, a sinistral spiracle, and welldefined jaw sheaths. Tadpole growth may be extended, with some tadpoles recurrently overwintering and finishing their growth the next year. Generally, tadpoles are medium-sized, but when they take two years to develop, may be fairly massive.

Conservation standing

Although not listed (with one exception) by the IUCN or CITES, most populations are declining due to habitat destruction. Pelodytes caucasicus is categorized as Data Deficient by the IUCN; it's also listed within the Red Data Books of Russia, Georgia, and Azerbaijan and within the Bern Convention (Annex 2). Pelodytes punctatus is listed as endangered by the nationwide requirements of Belgium, Luxembourg, France, and as susceptible within the different international locations the place it's discovered.
