Animals
Animals are a major group of organisms, classified as the kingdom Animalia or Metazoa. In general they are multi cellular, capable of locomotion at some stage in their life cycle, responsive to their environment, and feed by consuming other organisms or parts of them. 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.
The word "animal" comes from the Latin word animal, of which animalia is the plural, and is derived from anima, meaning vital breath or soul. In everyday colloquial usage, the word usually refers to non-human animals. The biological definition of the word refers all members of the Kingdom Animalia. Therefore, when the word "animal" is used in a biological context, humans are included.
