Gastric-brooding Frog

Gastric-brooding Frog

The gastric-brooding frogs or Platypus frogs (Rheobatrachus) were a genus of ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus was unique because it contained the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother.

The combined ranges of the gastric-brooding frogs comprised less than 2,000 square kilometres (770 sq mi). Both species were associated with creek systems in rainforests at elevations of between 350 metres (1,150 ft) and 1,400 metres (4,600 ft). The causes of the gastric-brooding frogs' extinction are not clearly understood, but habitat loss and degradation, pollution, and some diseases may have contributed.

The assignment of the genus to a taxonomic family is hotly debated. Some biologists class them within Myobatrachidae under the subfamily Rheobatrachinae, but others place them in their own family, Rheobatrachidae.

    A frog he would a-wooing go,
    Heigh ho! says Rowley,
    Whether his mother would let him or no.
    With a rowley, powley, gammon and spinach,
    Heigh ho! says Anthony Rowley.
