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.
The genus Crinia contains 17 species: [1]

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.
Johann Jakob von Tschudi was a Swiss naturalist, explorer and diplomat.
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.
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.
The common eastern froglet is a very common, Australian ground-dwelling frog, of the family Myobatrachidae.
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.
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.
The dainty green tree frog, also known as the graceful tree frog, is a tree frog native to eastern Queensland, and north-eastern New South Wales, Australia. It ranges from northern Cape York in Queensland to Gosford in New South Wales, with a small and most likely introduced population in Hornsby Heights in Sydney. It is the faunal emblem of the City of Brisbane.
The eastern sign-bearing froglet is a small, ground dwelling frog native to eastern Australia.
The streambank froglet or Flinders Ranges froglet is a small, locally common, Australian ground-dwelling frog, of the family Myobatrachidae.
Boophis is the only genus in the mantellid frog subfamily Boophinae. They are commonly known as bright-eyed or skeleton frogs. They show typical 'tree frog' traits, and are a good example of convergent evolution with morphologically similar species in the families Hylidae and Rhacophoridae, among others. This genus can only be found on Madagascar and Mayotte Island (Comoros).
The desert froglet is a species of frog in the family Myobatrachidae, endemic to Australia. The species is not under any threat of extinction. Desert froglets occur mainly in dry or moist savanna habitats, principally from the mid-western border of Northern Territory, south-east into western Queensland and New South Wales and the north-east corner of South Australia. They can also be found along the Queensland coast where it has been recorded between Townsville and Cooktown, and as far south as Hervey Bay.
The quacking frog also known as the red-thighed froglet is a species of frog in the family Myobatrachidae. It is endemic to Australia. Its call has been described as closely resembling the quack of a duck.
Sloane's froglet is a species of frog in the family Myobatrachidae. It is endemic to Australia. Its natural habitats are subtropical or tropical seasonally wet or flooded lowland grassland and intermittent freshwater marshes in and around the floodplains of the Murray-Darling Basin
Geocrinia rosea, the Karri or Roseate Frog is a species in the family, Myobatrachidae. It is endemic to Southwest Australia.
Raorchestes nerostagona is a species of frog in the family Rhacophoridae. It is endemic to the Western Ghats, India. It is sometimes known as the Kalpetta yellow bush frog. It is also called the lichen bush frog for its patchy lichen like patterning that make it cryptic. First described in 2005 based on a specimen obtained in Kalpetta, the species has subsequently found to be distributed in many parts of the Western Ghats.
The Ceratobatrachidae are a family of frogs found in the Malay Peninsula, Borneo, the Philippines, Palau, Fiji, New Guinea, and the Admiralty, Bismarck, and Solomon Islands.
Raorchestes resplendens, the resplendent shrubfrog, is a critically endangered species of frogs belonging to the family Rhacophoridae endemic to the high altitude region around the south Indian peak of Anaimudi. It has extremely short limbs and numerous macroglands and was discovered from the Anamudi summit in the Western Ghats of Kerala, India and is known only from the Eravikulam National Park.
Raorchestes is a genus of frogs in the subfamily Rhacophorinae that are found in mountainous regions of South Asia, Southeast Asia, and southern China. A recent study places Raorchestes as a sister taxon of Pseudophilautus. Before the description of the genus in 2010, species now in Raorchestes had been assigned to genera Ixalus, Philautus, and Pseudophilautus.
The northern Flinders Ranges froglet, or Flinders Springs froglet, is a species of small frog that is endemic to Australia.
