Pig[note 11]
Pig, wild or domestic swine, a mammal of the Suidae family. In Britain, the term pig refers to all domestic swine; in the United States,
 to younger swine not yet ready for market and weighing usually less 
than 82 kg (180 pounds), others being called hogs. Pigs are 
stout-bodied, short-legged, omnivorous mammals, with thick skins usually
 sparsely coated with short bristles. Their hooves have two functional 
and two nonfunctional digits. Domestic North American pigs originated 
from wild stocks still found in European, Asian, and North African 
forests.
