Warthogs are very sturdy animals and males can weigh over 110 kilograms. They are distinguished by the large, disproportionate ‘warts’ on either side of the head. These ‘warts’ are in fact thick protective pads. The warthog has two long upper tusks that form a semi circle and two lower tusks that are worn to a sharp-cutting edge. To graze on short grass warthogs have developed the practice of kneeling on their calloused, padded knees and they use their snouts to dig for bulbs and roots.
Male warthogs are called boars, females are called sows, young are referred to as piglets and a group of warthogs is known as a sounder.
