The wild boar (Sus scrofa) is an omnivorous, gregarious mammal of the biological family Suidae. 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.

The Domestic Pig (Sus scrofa domesticus) is usually given the scientific name Sus scrofa, though some authors call it S. domesticus, reserving S. scrofa for the Wild boar.

Zebus (Bos primigenius indicus), sometimes known as 'humped cattle' or 'indicus' cattle, are a type of cattle better-adapted to tropical environments than the other domestic cattle, the Bos primigenius taurus or 'taurine' types^{[citation needed]}. The scientific name of zebu cattle was originally Bos indicus, but this name is now deemed invalid by ITIS, who classify the zebu under Bos primigenius along with all other domestic cattle and their extinct aurochs ancestors. However, domestic cattle are sometimes regarded as a separate species to the aurochs, in which case Zebu are known as Bos taurus indicus.
