The diet of the Schilluk ridged frog mostly consists of large, active, terrestrial invertebrates such as spiders, cockroaches, crickets and grasshoppers (2). It may also feed on other frogs (1), with one specimen being seen to eat a closely related species, Ptychadena mascareniensis, that was a third of its own size (3).
Many sightings of the Schilluk ridged frog occur during the daytime, which suggests that this is when it is most active (3). The Schilluk ridged frog usually breeds in flooded areas such as rice fields or flooded grassland, created by the first rainfalls (1) (2). The males have been seen calling to females while partially submerged in water, at the base of tufts of grass, as well as while floating at the water’s surface (2).
The Schilluk ridged frog lays small, brown-white eggs (2). Little other information is available on the breeding behaviour of this species.
