Warthog
Warthogs are members of the pig family found in sub-Saharan Africa, known for their prominent tusks and their knobby, bumpy faces.
Class: Mammalia
Order: Artiodactyla
Family: Suidae
Genus: Phaochoerus
Species: P. africanus, P. aethiopicus
Warthog groups are called “sounders”. Most sounders are composed of females and their young. Young males live in “bachelor” groups with other males, but become solitary when they reach adulthood.
Warthogs live mostly in grassland and savanna habitats, where they feed mostly on grasses, roots, berries, fruits, and occasionally insects and eggs. Warthogs use their snouts and tusks to dig out roots and other food items when grasses are not available.
Warthogs live in burrows, usually those abandoned by other animals such as aardvarks. Thought they can defend themselves and their young with their tusks if necessary, their main defense mechanism is to run away from potential threats. Predators of warthogs include humans, lions, leopards, cheetahs, crocodiles, hyenas and African wild dogs.
Warthogs gestate for five to six months, giving birth to between two and four piglets typically. Occasionally, litters can number as high as eight piglets. The sow (female warthog) and her babies will stay in a special hole away from the rest of the sounder to nurse her piglets. Young warthogs begin to feed on their own by grazing at around three weeks old, and are completely weaned by half a year.
The warthog is a medium sized member of the pig family, growing to almost five feet in length, and weighing as much as 330 pounds. They have very distinctive heads, with long faces covered in knobby protrusions, and prominent tusks sprouting from their mouths.
They have a mane of hair running down the back, and short bristles of fur covering their bodies.
Warthogs, as members of the pig family, are “even-toed ungulates” in the order Artiodactyla, the same group as hippos, camels, deer, giraffes, antelopes, goats, and even whales and dolphins.
The suborder Suina, which contains pigs and peccaries, first appeared in the late Eocene Epoch, almost 34 million years ago. Fossil evidence shows that the two current species of warthog first diverged from a common ancestor thousands of years ago.
Both living species of warthog are considered “Least Concern” by the International Union for the Conservation of Nature (IUCN).However, a subspecies of the desert warthog, known as the Cape warthog, went extinct in its range of South Africa in the 1870s.
