The red river hog (Potamochoerus porcus), also known as the bush pig (but not to be confused with P. larvatus, common name "bushpig"), is a wild member of the pig family living in Africa, with most of its distribution in the Guinean and Congolian forests. It is rarely seen away from rainforests, and generally prefers areas near rivers or swamps.
The red river hog has striking orange to reddish-brown fur, with black legs and a tufted white stripe along the spine. Adults have white markings around the eyes and on the cheeks and jaws; the rest of the muzzle and face are a contrasting black. The fur on the jaw and the flanks is longer than that on the body, with the males having especially prominent facial whiskers. Unlike other species of pig native to tropical Africa, the entire body is covered in hair, with no bare skin visible.
Adults weigh 45 to 115 kg (99 to 254 lb) and stand 55 to 80 cm (22 to 31 in) tall, with a length of 100 to 145 cm (39 to 57 in). The thin tail is 30 to 45 cm (12 to 18 in) long and ends in a tuft of black hair. The ears are also long and thin, ending in tufts of white or black hair that may each 12 cm (4.7 in) in length. Boars are somewhat larger than sows, and have distinct conical protuberances on either side of the snout and rather small, sharp tusks. The facial protuberances are bony and probably protect the boar's facial tendons during head-to-head combat with other males.
Red river hogs have a dental formula of 3.1.3-4.33.1.3-4.3, similar to that of wild boar. Both sexes have scent glands close to the eyes and on the feet; males have additional glands near the tusks on the upper jaw and on the penis. There is also a distinctive glandular structure about 2 cm (0.79 in) in diameter on the chin, which probably has a tactile function. Females have six teats.
The red river hog lives in rainforests, wet dense savannas, and forested valleys, and near rivers, lakes and marshes. The species' distribution ranges from the Congo area and Gambia to the eastern Congo, southwards to the Kasai and the Congo River. The exact delineation of its range versus that of the bushpig is unclear; but in broad terms, the red river hog occupies western and central Africa, and the bushpig occupies eastern and southern Africa. Where the two meet, they are sometimes said to interbreed, although other authorities dispute this. Although numerous subspecies have been identified in the past, none are currently recognised.
