Du Toit's torrent frog is found in and around the rocky montane streams of Mount Elgon, Kenya, associated with fast flowing streams and waterfalls. The eggs are laid on wet rocks close to torrential streams, and the tadpoles develop clinging to these vertical rock surfaces and grazing algae. It was officially described as a new species in 1935, but has not been seen on Mount Elgon since 1962, despite its habitat being of generally good quality. In view of the rapid disappearance of other montane stream-dwelling species elsewhere in the humid tropics, the impact of disease, such as chytridiomycosis, is a plausible cause of this species’ dramatic decline and possible extinction.
