The aurochs is an extinct cattle species, considered to be the wild ancestor of modern domestic cattle. With a shoulder height of up to 180 cm (71 in) in bulls and 155 cm (61 in) in cows, it was one of the largest herbivores in the Holocene; it had massive elongated and broad horns that reached 80 cm (31 in) in length.

The zebu, sometimes known in the plural as indicine cattle, Camel cow or humped cattle, is a species or subspecies of domestic cattle originating in South Asia. Zebu, like many Sanga cattle breeds, differs from taurine cattle by a fatty hump on their shoulders, a large dewlap, and sometimes drooping ears. They are well adapted to withstanding high temperatures and are farmed throughout the tropics.
