Ptychadena nilotica (Seetzen, 1855)

Vouchers: NMK-A1818 (field nos. SK16 1045, SK16 1046, SK16 1056, SK16 1058, SK16 1065– 1068, SK16 1070, SK16 1097, SK16 1105) Localities: IL (G), AB ( R), KF (G)

Remarks: This species ( Fig. 3D ) was found in high numbers. Individuals were found at night together with Sclerophrys turkanae in flooded grassy plains along the shore of Lake Turkana, but also on the edge of temporarily flooded waterbodies and in the riverbed transects slightly further away from the actual lake shore where S. turkanae was mostly absent. When disturbed at the water edge on land, individuals of P. nilotica escaped by jumping into the lake, but instead of diving into the water, they rather jumped across the water surface for several meters without sinking before jumping back on land.
