Crinia is a genus of frog, native to Australia, and part of the family Myobatrachidae. It consists of small frogs, which are distributed throughout most of Australia, excluding the central arid regions. Many of the species within this genus are non-distinguishable through physical characteristics, and can only be distinguished by their calls.

They have unwebbed toes and fingers, most of the species in these genus are polymorphic - meaning that several variations of colour and skin patterning exist in a single population and all species lay their eggs in small clumps in water.

The generic name Crinia likely derives from the Greek verb κρῑνω (krīnō) "to separate" as a reference to the frog's unwebbed digits, meaning "separated (toes)." Although Johann Jakob von Tschudi did not provide an etymology in 1838, he cited the frog's "free toes" (without webbing) as an important distinctive feature (most frogs have webbed feet).

During the 1950s, 1960s and 1970s a lot of taxonomic work was done on this genus, frogs that were originally thought to be common eastern froglets (Crinia signifera) were described as other species of Crinia by mating call analysis and hybridization experiments. Two species originally described as Crinia were then placed in their own genus, Assa and Paracrinia . One species of both Geocrinia and Taudactylus were split from Crinia and the genus Bryobatrachus was also described only to be recently placed back into Crinia. The moss froglet, (Crinia nimbus) is very different physically and in its tadpole development. Due to the obvious differences with other species in Crinia this species is likely to be placed again into a separate genus.

True frog Family of frogs

The true frogs, family Ranidae, have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa, and Asia. The Asian range extends across the East Indies to New Guinea and a single species has spread into the far north of Australia.

Leptodactylidae Family of amphibians

The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes. They are a diverse family of frogs that most likely diverged from other hyloids during the Cretaceous. The family has undergone major taxonomic revisions in recent years, including the reclassification of the former subfamily Eleutherodactylinae into its own family the Eleutherodactylidae; the Leptodactylidae now number 206 species in 15 genera distributed throughout Mexico, the Caribbean, and Central and South America. The family includes terrestrial, burrowing, aquatic, and arboreal members, inhabiting a wide range of habitats.

Microhylidae Family of amphibians

The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family.

Common eastern froglet Species of amphibian

The common eastern froglet is a very common, Australian ground-dwelling frog, of the family Myobatrachidae.

<i>Theloderma</i> Genus of amphibians

Theloderma, the bug-eyed frogs, mossy frogs or warty frogs, is a genus of frogs in the family Rhacophoridae, subfamily Rhacophorinae. They are found from northeastern India and southern China, through Southeast Asia, to the Greater Sunda Islands; the highest species richness is in Indochina. Some species, especially T. corticale, are sometimes kept in captivity.

<i>Taudactylus</i> Genus of amphibians

Taudactylus is a genus of frogs in the family Myobatrachidae. These frogs are endemic to rainforest areas of coastal eastern Australia, most of this genus inhabit fast flowing streams in highland area. Most members of this genus have suffered serious declines, in which the disease chytridiomycosis appears to have played a significant role: T. diurnus is believed to be extinct, while all others except T. liemi are listed as critically endangered by the IUCN. These listings are conservative, and it is likely T. acutirostris, presently listed as critically endangered, already is extinct.
