The common eastern froglet (Crinia signifera) is a very common, Australian ground-dwelling frog, of the family Myobatrachidae.
The common eastern froglet ranges from southeastern Australia, from Adelaide to Melbourne, up the eastern coast to Brisbane. It also inhabits a majority of Tasmania. It is one of the most commonly encountered frog species within its range, due to its ability to occupy several habitat types.
The common eastern froglet is a small frog (3 centimetres), of brown or grey colour of various shades. The frog is of extremely variable markings, with great variety usually found within confined populations. A dark, triangular mark is found on the upper lip, with darker bands on the legs. A small white spot is on the base of each arm. The dorsal and ventral surfaces are very variable. The dorsal surface may be smooth, warty or have longitudinal skin folds. The colour varies from dark brown, fawn, light and dark grey. The colour of the ventral surface is similar to the dorsal surface, but mottled with white spots.
The common eastern froglet will call within a large chorus of males close to a still water source, or slow flowing creek. The call of the male is a crik-crik-crik; this is heard all year round, during wet and dry conditions. An average of about 200 eggs are laid in small clusters attached to submerged vegetation. The tadpoles and eggs survive in 14–15 °C water. Tadpoles are normally brown and reach about 36mm in length. Development is relatively short and dependent on environmental conditions. At a temperature of 15 °C development can range from 6 weeks to more than 3 months. Metamorph frogs are very small, about 8 mm.
The diet of the species consists of small insects, much smaller in comparison to their size than most frogs.
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.
The giant barred frog is a species of barred frog found in Australia. It occurs from south-eastern Queensland to just south of the Newcastle region in New South Wales. It is associated with flowing streams and creeks in wet sclerophyll and rainforest habitats from the coast to the ranges.
The Tasmanian froglet is a species of ground-dwelling frog that occurs only in Tasmania, Australia.
The red-crowned toadlet is a species of Australian ground frog, restricted to the Sydney Basin, New South Wales. It is only found around sandstone escarpment areas around Sydney, from Ourimbah in the north, Nowra to the south and the Blue Mountains areas to the west.
The red-backed toadlet is a species of ground frog native to the coast and adjacent ranges of eastern Australia, from just north of Sydney to South-eastern Queensland.
The wallum froglet is a species of ground-dwelling frog native to the east coast of Australia, from southeast Queensland to Kurnell, NSW. It is strongly associated with Wallum swampland.
The leaf green tree frog is a species of stream-dwelling frog, native to eastern Australia from the Queensland/New South Wales border south to Sydney.
The Tasmanian tree frog, also known as king tree frog, is a species of tree frog that is found on the west coast of Tasmania, Australia. It was first found by Myrtle Burrows in 1941, at Cradle Mountain and handed over to Oswald Scott, who is attributed with the discovery.
Haswell's frog is a small ground frog found around coastal swamps in eastern Australia from around Port Macquarie, New South Wales to the Mornington Peninsula in Victoria. It is the only member of the genus Paracrinia.
The tusked frog is a species of ground-dwelling frog native to eastern Australia from Eungella National Park, Queensland south to Ourimbah, New South Wales. It is the only species in the genus Adelotus - adelotus meaning "unseen" and brevis meaning "short".
Fleay's barred frog is a large species of frog restricted to small pockets of rainforest in northern New South Wales and south-eastern Queensland, Australia.
The western chorus frog, also known as striped chorus frog, or midland chorus frog is a species of frog found in Canada and the United States.
The ornate burrowing frog is a species of ground frog native to Australia. It was moved to the genus Opisthodon in 2006, following a major revision of amphibians, and is now classified in the genus Platyplectrum.
The Sudell's frog, painted burrowing frog, trilling frog or desert trilling frog is a species of burrowing frog common to a large part of southeastern Australia. It is found on and west of the Great Dividing Range of New South Wales to western Victoria and southern Queensland, as well as far eastern South Australia, and southern regions of the Northern Territory.
The wrinkled toadlet is a species of small, ground-dwelling frog in the family Myobatrachidae It is endemic to Australia. It is also commonly called the small-headed toadlet, red-groined toadlet or the chubby gungan.
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.
The desert froglet is a species of frog in the family Myobatrachidae, endemic to Australia. 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 due to its legs tending to be bright red. It is a species of frog from the Myobatrachidae family and is in a clad with five other species. The frog is well known for the sound it produces which resembles a quack. It has up to 11 notes and can change the notes in their call. It has larger testes compared to other frogs within the genus and has started to be used in experiments. This frog is found in southwest Australia. It is found in ponds and pools and other moisture filled areas. These frogs engage in polyandry and can result in multiple paternity of its offspring. Additionally, the tadpoles of this species can change the rate they metamorphosize depending on the conditions. The males tend to have larger arm girth and can adopt different mating strategies depending on size. The mating strategy is dependent on male density. The frogs also vary in terms of color and texture of its skin. The tadpoles are generally golden with transparent tails.
The northern Flinders Ranges froglet, or Flinders Springs froglet, is a species of small frog that is endemic to Australia.
