boar

n. wild hog or pig; uncastrated male swine

The wild boar (Sus scrofa) is the wild ancestor of the domestic pig. It is native across much of Central Europe, the Mediterranean Region (including North Africa's Atlas Mountains) and much of Asia as far south as Indonesia, and has been widely introduced elsewhere. It is in the same Suidae biological family as the Warthog and Bushpig of Africa, the Pygmy Hog of northern India, Babirusa of Indonesia and others.
