==Description==
==Description==
'''Animals''' are a major group of multicellular, eukaryotic [[organisms]] of the kingdom Animalia or Metazoa. Their [[body]] plan eventually becomes fixed as they [[develop]], although some undergo a process of [[metamorphosis]] later on in their [[life]]. Most animals are motile, meaning they can move [[spontaneously]] and independently. All animals are also [http://en.wikipedia.org/wiki/Heterotroph heterotrophs], meaning they must ingest other organisms or their products for sustenance.
