The Cape River Frog has a particularly wide rounded snout, large, upwardly protruding eyes within the outline of the head, and large tympanums. The hind legs are long and muscular, and the toes are fully webbed. Its skin is smooth, with longitudinal folds on the back.
Colouraion varies from light brownish to olive-green. The specific name fuscigula refers to the dark mottling on the throat. The back is usually marked with darker stripes and spots. The lower lip is mottled, while the upper lip is uniformly dark. There is no dark blotch on the snout.
It may have a yellow or white stripe down the middle of its back. The underside is white.

Size
Male average 75 mm. Female average 90 mm; up to 125 mm.

Behaviour

Call
