Definition: a common mode of asexual reproduction among skeletonless coelenterates and also in some skeletal anthozoans (division of the soft body must be associated with division of the skeleton)
Definition: Colonial organisms are clonal colonies composed of many physically connected, interdependent individuals. The subunits of colonial organisms can be unicellular, as in the alga Volvox (a coenobium), or multicellular, as in the phylum Bryozoa. The former type may have been the first step toward multicellular organisms
