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.
The southern gastric-brooding frog was discovered in 1972 and described in 1973, [2] though there is one publication suggesting that the species was discovered in 1914 (from the Blackall Range). [ 3 ] [ 4 ] Rheobatrachus silus was restricted to the Blackall Range and Conondale Ranges in southeast Queensland , north of Brisbane , between ...

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]
For example, the female gastric-brooding frog (Rheobatrachus sp.) from Australia, now probably extinct, swallows her fertilized eggs, which then develop inside her stomach. She ceases to feed and stops secreting stomach acid and the tadpoles rely on the yolks of the eggs for nourishment.

Myobatrachidae, commonly known as Australian ground frogs or Australian water frogs, is a family of frogs found in Australia and New Guinea. Members of this family vary greatly in size, from species less than 1.5 cm (0.59 in) long, to the second-largest frog in Australia, the giant barred frog ( Mixophyes iteratus ), at 12 cm (4.7 in) in length.
For example, in the frog species Bibron's Toadlet, male frogs are left to care for the nest. Parental care after the laying of eggs has been observed in 5% of caecilian species, 18% of salamander species and 6% of frog species, [ 45 ] though this number is likely an underestimate due to taxonomic bias in research [ 46 ] and the cryptic nature ...
