Distribution and habitat
It is found in Kenya, Tanzania, Malawi, Mozambique, Zimbabwe, South Africa and possibly Swaziland. Its natural habitats are temperate forest, subtropical or tropical dry forest, dry savanna, moist savanna, temperate shrubland, subtropical or tropical moist shrubland, temperate grassland, subtropical or tropical seasonally wet or flooded lowland grassland, swamps, freshwater marshes, intermittent freshwater marshes, water storage areas, and ponds.
Evidence for natural selection
The camouflage mechanism used by the species provided compelling evidence for evolution by natural selection. The zoologist Hugh Cott's drawings and description of the frog's "coincident disruptive coloration" showed that its pattern, forming bold stripes on the legs and body, lined up (coincided) exactly when the legs were tightly folded into the body at rest, effectively disrupting its outline. The zoologists I. C. Cuthill and A. Székely noted that the way the configuration works indicates that it must have survival value, implying natural selection at work.
