This frog goes by several common names: Eastern Banjo Frog, Eastern Pobblebonk Frog and Southern Bullfrog. The first two are based on its distinctive 'bonk' call which sounds similar to the string of a banjo being plucked.

Its back ranges from grey, to olive-green, dark brown or black, with dark marbling or flecks. It has a pale yellow stripe running from under its eye to its arm, a dark band above this, and may also have a pale stripe running down its back. Its sides commonly have a purple or bronze sheen, mottled with black. Its belly is white and sometimes mottled with grey. Its back is warty and rough but its belly is smooth.

Distinctive feature

A prominent gland on the outer side of its hind leg (its shin) and a fleshy lump at the base of each hind foot.
