Bei verschiedenen Nesseltieren (Cnidaria), den Catenuliden PlattwΓΌrmern oder den KelchwΓΌrmern (Ectroprocta) sind die einzelnen Zooide miteinander verwachsen.
Bei den Moostierchen (Bryozoa) und den FlΓΌgelkiemern (Pterobranchia) befinden sich die Zooide innerhalb einer WohnrΓΆhre (extrazooidales Skelett, Zooecium), die die verbindende Struktur der Kolonie darstellt.
Beim Manteltier (Tunicat) Botryllus schlosseri leben die Zooide in einer gemeinsamen extrazellulΓ€ren Matrix, der Tunica, und sind durch ein ringfΓΆrmiges BlutgefÀà miteinander verbunden, welches auΓerhalb der TierkΓΆrper verlΓ€uft.cite-ref-botryllus-1-1[1]cite-ref-2[2]
