Animal

Animals are a group of organisms, classified as the kingdom Animalia or Metazoa. In general they are multicellular, capable of locomotion and responsive to their environment, and feed by consuming other organisms. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on.

Biologically, humans fall under the animal kingdom, and are in this sense animals. However, sometimes confusion arises because the word is also used contrastively with human-- that is, to indicate non-human animals.
