The African giant toad, Congo toad,〔 or Cameroon toad (''Amietophrynus superciliaris'') is a species of toad in the family Bufonidae. It is found in Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Ivory Coast, Equatorial Guinea, Gabon, Ghana, Nigeria, possibly Liberia, and possibly Sierra Leone. The toad's natural habitats are subtropical or tropical moist lowland forests, freshwater marshes, intermittent freshwater marshes, plantations, and heavily degraded former forest. While it is a "least concern" species, it is threatened by habitat loss.〔 ==Taxonomy== The African giant toad appears to be a species complex. Although it is found across western and central Africa, it does not have a single large area of occupancy but occurs in several separate populations. It has been proposed〔 that the species should be divided into three separate taxa, two subspecies and a new species. The proposed subspecies are ''A. superciliaris superciliaris'', found only in the western Lower Guinean forests extending along the eastern coast of the Gulf of Guinea from eastern Benin through Nigeria, Cameroon and Equatorial Guinea, and ''A. superciliaris chevalieri'', found in the Upper Guinean forests of Sierra Leone, Guinea, Liberia, Ivory Coast and Ghana, and the new species, ''Amietophrynus channingi'', found in the eastern part of the Democratic Republic of Congo.〔
