Habitat and Ecology:It inhabits all biomes of South Africa, excluding the arid areas, such as forest, fynbos heath land, thicket, savannah and grassland, as well as modified habitats. It breeds in almost any well vegetated shallow body of water, such as pools, dams, ponds, ditches, and brackish pools along the coast within the spray zone, and shallow seeps. It can also tolerate polluted waters. It lays its eggs out of the water in moist situations, and the tadpoles enter the water to complete their development.
