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, Sclerophrys channingi, found in the eastern part of the Democratic Republic of Congo. The latter species has been described as a Batesian mimic of the venomous Gaboon viper. Description The African giant toad is a large species with a robust body which is a broad ovoid in shape. It has a short snout, an unridged crown and nearly-vertical sides to the head. The eyes are set close together and the upper eyelid has a pointed edge drawn out into a triangular projection. The tympanum is indistinct but the parotid glands are large. The first finger of the hand is longer than the second one, males having nuptial pads on the first two fingers. On the hind limbs, the toes are short and partially webbed. The skin on the back is either smooth or may bear small warts. The upper surface of the head and body is pale brown, yellowish or pinkish. There is a backwards-pointing V-shaped black mark between the eyes and there are sometimes one or more pairs of dark spots on the back. There is sometimes a thin, pale stripe running along the spine. The sides of the head and body are considerably darker than the upper parts. The underparts
