The desert warthog (Phacochoerus aethiopicus) is a species of even-toed ungulate in the pig family. This is the range of the extant subspecies, commonly known as the Somali warthog. Desert warthogs can be differentiated from the common warthog by their distinctive facial features, including curled back tips at the end of the ears, lack of incisors, and generally larger snout.
The desert warthog is a stockily-built animal with males being larger than females. It has a rather flattened head with distinctive facial paired protuberances (“warts”) and large curving canine teeth that protrude as tusks. The body is sparsely covered with bristly hairs and a more dense region of hairs runs along the spine and forms a crest. The tail is long and thin and is tipped with a small brush of coarse hair. The general colour is mid to dark brown but the crest is sometimes whitish.
