Which of these is a wild member of the pig family living in Africa?

The red river hog ('Potamochoerus porcus') 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.

The red river hog lives in rainforests, wet dense savannas, and forested valleys, and near rivers, lakes and marshes.

The species is omnivorous, eating mainly roots and tubers, and supplements its diet with fruit, grasses, herbs, eggs, dead animal and plant remains, insects, and lizards. It uses its large muzzle to snuffle about in the soil in search of food, as well as scraping the ground with their tusks and fore-feet.
