The Southern Toadlet has a warty, dark brown to olive green upper surface. The undersurface, however, is brilliantly patterned with marbled dark brown to black and bluish white. Indeed, the Southern Toadlet is a close relative of the well-known and vividly patterned Corroboree Frog of the southern alps of mainland Australia. The Southern Toadlet reaches a body length of 35 mm.


The species breeds in temporary ponds during from late summer to early autumn, during which time the males call can be heard. Clutches of up to 200 eggs are laid on land in a shallow nest constructed by the male. These nests become flooded with the onset of winter

Southern Toadlet

Males call from shallow nests built beneath soil or leaf litter during the autumn. Surprisingly, members of this genus of frog lack functional hearing apparatus. It is not known how they are able to hear airborne sounds, although one theory suggests that airborne sounds may be conducted through the bones of the skull.

Distribution and Habitat

The Southern Toadlet is found from central to eastern Tasmania and Flinders Island, where it prefers open forest, grasslands and sedgelands. It is also found in southern Victoria and South Australia.

Strictly speaking, there are no toads in Australia, with the exception of the introduced cane toad. However, many Australian species, including the Southern Toadlet, are commonly known as toads or toadlets. This has arisen due to their superficial similarity to the warty toads that were familiar to the first European settlers.
