Zebus (Bos primigenius indicus), sometimes known as 'humped
cattle' or 'indicus' cattle, are better-adapted to
tropical environments than the other domestic
cattle, the Bos primigenius taurus or 'taurine' types. 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.
