Boars

The wild, suidae boars can be a dangerous prey for hunters, due to their sharps tusks and strong hooves.

Description
Despite the dangers, however, hunters make boars their primary targets, since their meat is delicious and usually considered to be worth the danger of hunting them for it. Legend has it that the humanoid orcs were originally created by genetically mating humans with wild boars.

Boars can be found everywhere in the wilderness, though they do prefer forests.

Trivia

 * Even though alive boars are only seen on the Serpent Isle, they have to exist on Britannia as well, since otherwise it would be baffling where the name of the Blue Boar Tavern comes from. Pigs (or boar) after all do exist when looking at the intro of Ultima Underworld II.
