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 ...
Distribution of the northern gastric-brooding frog (blue) The northern gastric-brooding frog ( Rheobatrachus vitellinus ) was discovered in 1984 by Michael Mahony. [ 2 ] It was restricted to the rainforest areas of the Clarke Range in Eungella National Park and the adjacent Pelion State Forest in central eastern Queensland.
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 ...
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.
Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg. Multiple and various factors are vital to the incubation of various species of animal. In many species of reptile for example, no fixed temperature is necessary, but the actual temperature determines the sex ratio of the offspring .
Gastric brooding frog: (2013) The gastric brooding frog, Rheobatrachus silus, thought to have been extinct since 1983 was cloned in Australia, although the embryos died after a few days. [76] Macaque monkey: (2017) First successful cloning of a primate species using nuclear transfer, with the birth of two live clones named Zhong Zhong and Hua ...
