A warthog is identifiable by the two pairs of tusks protruding from the mouth and curving upwards. The head of the common warthog is large, with a mane down the spine to the middle of the back. Sparse hair covers the body. Its colour is usually black or brown. Tails are long and end with a tuft of hair. Common warthogs do not have subcutaneous fat and the coat is sparse, making them susceptible to extreme environmental temperatures.
