401:. It prefers permanent water and commonly colonises dams and other artificial water bodies, but in some regions it is limited to seasonal transient water bodies. Where it occupies farm dams, it commonly emerges during the morning and takes up an inconspicuous position on the bank where it basks until the sun becomes too intense near noon. While basking, it is much sought by predators such as

streams, they mature more rapidly into smaller juvenile frogs. A typical size for a mature tadpole is about 80 mm, but in deep, cool, permanent water, they might grow to twice that length. In warm shallow water with plenty of food, the period of development may take about 9 months to a year, but in cold, deep water with little food, it might take two years.

The Cape river frog is a fairly large, typical frog with a snout-to-vent measurement of up to about 125 mm. The snout is slightly rounded. It has a powerful, athletic build with long hind legs and feet, well adapted for leaping, but also well webbed; the species is a powerful swimmer. The fore

When it occupies streams and ditches, the Cape river frog prefers deep ponds such as occur below inlets and races where the turbulent flow hollows out convenient shelters. It also prefers deep, still water for its breeding, where its tadpoles grow fairly slowly, but achieve a large size; in shallow

The voice is confusingly variable, particularly where it occurs together with several other noisy species. Males may call at any time of the year in various regions, but calling peaks in the breeding season. Typically, a call begins with a rattle of clicks about 0.1 seconds apart, like a slowly
