This species ranges from southern Guinea-Bissau, through western Guinea, to southern Sierra Leone.
Habitat and Ecology
It is a water-dependent species, and is usually found in still water, milky, silt-laden water, shaded by trees in lowland forest, including secondary forest. However, it has also been found in small, very slow-moving rocky streams, and in water in agricultural land, providing that the water remains shaded. It can thrive in newly created aquatic habitats, which it readily colonizes overland. It avoids waterbodies with large fish populations. It breeds in water and has predatory tadpoles.
It is a common species where it occurs.
The main threat might be harvesting for local human consumption. The animals are caught with wicker trays. Removal of shade trees and introduction of predatory fish might also be threats, at least locally. However, it is thought that the species is not seriously threatened.
It has not been confirmed from any protected areas, and there are very few within its range.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its relatively wide distribution, it tolerance of a degree of habitat modification and its presumed large population.
