Warthogs range in size from 0.91 to 1.5 m (3.0 to 4.9 ft) in length and 50 to 75 kg (110 to 170 lb) in weight.
A warthog is identifiable by the two pairs of tusks protruding from the mouth and curving upwards. The lower pair,
which is far shorter than the upper pair, becomes razor sharp by rubbing against the upper pair every time the mouth
is opened and closed. The upper canine teeth can grow to 23 cm (9.1 in), and are of a squashed circle shape in cross
section, almost rectangular, being about 4.5 cm (1.8 in) deep and 2.5 cm (0.98 in) wide. The tusk will curve 90 degrees
or more from the root,[citation needed] and the tusk will not lie flat on a table, as it curves somewhat backwards as
it grows. The tusks are used for digging, for combat with other hogs, and in defence against predators—the lower set
can inflict severe wounds. ~wiki~
