The Domestic Pig typically has a large head, with a long snout which is strengthened by a special prenasal bone and a disk of cartilage at the tip. Adult pigs have about a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth can form tusks, which grow continuously and are sharpened by constantly being ground against each other.
Domestic Pigs can be found nearly everywhere except Antarctica.
The lifespan of the Domestic Pig is 15 - 20 years.
The Domestic Pig's head-plus-body-length ranges from 0.9 to 1.8 metres, and the adult can weigh between 50 to 350 kilograms.
The Domestic Pig is an omnivore. In the wild, they are foraging animals, primarily eating leaves, grasses, roots, fruits, and flowers. In confinement, pigs are fed mostly corn and soybean meal.
Wild habitat is generally moist forests, swamps and shrublands, especially oak forests and regions where reeds are abundant.
A pig's gestation period is 3 months, 3 weeks and 3 days.
