Warthogs are easily distinguishable from other hogs because of the wartlike protuberances on either side of their heads, behind and under their eyes and on the jaw. Actual warts (skin growths) are only prominent on males. Warthog sows (females) and their young live in groups called sounders, which typically consist of 3-10 individuals. Male boars tend to live in solitude or in bachelor groups. Warthogs are not particularly territorial, but sounders will avoid each other and males will mark trees with their tusks and tusk-gland secretions. When eating, warthogs drop onto their padded wrists – a behavior unique among pigs. Because they are incapable of sweating, warthogs often wallow in mud to cool off and repel insects.
