Rheobatrachus, whose members are known as the gastric-brooding frogs or platypus frogs, is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, the southern and northern gastric-brooding frogs, both of which became extinct in the mid-1980s.
In 1976, the Southern gastric-brooding frog's population was estimated at 78 individuals in the Booloumba Creek and Conondale Range regions. [4] The Southern gastric-brooding frog suffered from population decline after the winter of 1979. [4] The last recording of the frog in the wild was 1981. [4] In 1983, the last known captive specimen died. [4]
The call was loud, consisting of several staccato notes. It was similar to the southern gastric-brooding frog's call although deeper, shorter and repeated less often. The northern gastric-brooding frog was observed feeding on caddisfly larvae and terrestrial and aquatic beetles as well as the Eungella torrent frog (Taudactylus eungellensis). [6]

Frog populations have declined dramatically since the 1950s. More than one-third of frog species are considered to be threatened with extinction, and more than 120 species are believed to have become extinct since the 1980s. [202] Among these species are the gastric-brooding frogs of Australia and the golden toad of Costa Rica.
Gastric-brooding frog – An entire genus of ground frogs that were native to Queensland, Australia. They became extinct in the mid-1980s primarily due to Chytridiomycosis. In 2013, scientists in Australia successfully created a living embryo from non-living preserved genetic material, and hope that by using somatic-cell nuclear transfer ...
The frog, scientific name Zhangixalus thaoae, joins nine other tree frogs from the same genus that call Vietnam home, the researchers said. While discovered in Vietnam, similar species are found ...
Some animals have a common name that includes the word 'brood' or its derivatives, although it is arguable whether the animals show 'broodiness' per se. For example, the female gastric-brooding frog ( Rheobatrachus sp. ) from Australia , now probably extinct, swallows her fertilized eggs, which then develop inside her stomach.
