It is variously considered a subspecies of ''Sus scrofa'' (the wild boar or Eurasian boar) or a distinct species. The pig's head-plus-body length ranges from , and adult pigs typically weigh between , with well-fed individuals even exceeding this range. The size and weight of hogs largely depends on their breed. Compared to other artiodactyls, a pig's head is relatively long and pointed. Most even-toed ungulates are herbivorous, but pigs are omnivores, like their wild relative. Pigs grunt and make snorting sounds. When used as livestock, pigs are farmed primarily for the production of meat, called pork. A group of pigs is called a ''passel'', a ''team'', or a ''sounder''.

Sus (genus)
''Sus'' is the genus of wild and domestic pigs, within the even-toed ungulate family Suidae. ''Sus'' include domestic pigs (''Sus domesticus'') and their ancestor, the common Eurasian wild boar (''Sus scrofa''), along with other species. ''Sus'' species, like all suids, are native to the Eurasian and African continents, ranging from Europe to the Pacific islands. Suids other than the pig are the babirusa of Indonesia, the pygmy hog of South Asia, the warthogs of Africa, and other pig genera from Africa. The suids are a sister clade to peccaries. Juvenile pigs are known as piglets. Pigs are highly social and intelligent animals. With around 1 billion of this species alive at any time, the domestic pig is among the most populous large mammals in the world. Pigs are omnivores and can consume a wide range of food. Pigs are biologically similar to humans and are thus frequently used for human medical research. Etymology The '' Online Etymology Dictionary'' provides anecdotal ev ...
