Th …Bryozoa. : Life History and Ecology. Bryozoans can reproduce both sexually and asexually. Asexual reproduction occurs by budding off new zooids as the colony grows, and is this the main way by which a colony expands in size. If a piece of a bryozoan colony breaks off, the piece can continue to grow and will form a new colony.Corals and Bryozoa Corals (Phylum Cnidaria) and bryozoans (Phylum Bryozoa) are two common Paleozoic groups. Skeletons of the two groups are superficially similar, but the animals are very different and unrelated to each other.
