A zooid or zoöid /ˈzoʊ.ɔɪd/ is a single animal that is part of a colonial animal. This lifestyle has been adopted by animals from separate unrelated taxa. Zooids are multicellular; their structure is similar to that of other solitary animals. The zooids can either be directly connected by tissue (e.g. corals, Catenulida, Siphonophorae, Pyrosome or Ectoprocta) or share a common exoskeleton (e.g. Bryozoa or Pterobranchia). The colonial organism as a whole is called a zoon /ˈzoʊ.ɒn/, plural zoa (from Ancient Greek zôion ζῷον meaning animal; plural zôia, ζῷα).
