The stank hog is somewhat larger than its cousin, the common wild swine, reaching a shoulder height of 40 inches, a length of six feet, and weighing up to 500 pounds. Protruding from an elongated muzzle, a single set of curved and pointed tusks reaches a length of 10 to 12 inches upon maturity. Stank hogs are nearly devoid of fur, with only sparse, bristly hairs poking upward from their thick, dark-gray hides. Each of its feet has four toes that end in two larger frontal hooves and two smaller rear hooves. Its short tail ends with a tuft of bristly hair and twitches when the animal is agitated.
