Animals are a major group of organisms, classified as the kingdom Animalia or Metazoa. In general they are multicellular, capable of locomotion, 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.
The word "animal" comes from the Latin word animal, of which animalia is the plural, and ultimately from anima, meaning vital breath or soul.
Characteristics
Animals have several characteristics that set them apart from other living things. Animals are
eukaryotic and usually
multicellular (although see
Myxozoa), which separates them from
bacteria and most
protists. They are
heterotrophic, generally digesting food in an internal chamber, which separates them from
plants and
algae. They are also distinguished from plants, algae, and
fungi by lacking
cell walls.
