The warthog or common warthog is a wild member of the pig family found in grassland, savanna and woodland in sub
Almost the entire body is covered with bristles which are either dark brown or black and rather coarse. This mammal is recognizable by the quills that run along the head, nape, and back that can be raised into a crest. Hence the name crested porcupine. There are also some sturdier quills which are about 35 cm (14 in) in length and run along the sides and back half of the body. These sturdier quills are used, for the most part, for defence and are usually marked with light and dark bands which alternate; these are not firmly attached. This porcupine has a shorter tail which has rattle quills at the end. The rattle quills broaden at the terminal end and the broad portion is hollow with thin walls. When these quills are vibrated they produce a hiss-like rattle.
The crested porcupine is for the most part herbivorous, eating roots, bulbs, crops. But occasionally they do consume insects, small vertebrates and carrion-Saharan Africa.
The common name comes from the four large, wart-like protrusions found on the head of the warthog, which serve as a fat reserve and are used for defence when males fight.
Warthog ivory is taken from the constantly growing canine teeth. The tusks, more often the upper set, are worked much in the way of elephant tusks with all designs scaled down.
The warthog is the only pig species that has adapted to grazing and savanna habitats. Its diet is omnivorous, composed of grasses, roots, berries and other fruits, bark, fungi, insects and eggs.
