Individuals of bryozoan colonies (called zooids) share the basic anatomy of bryozoans, namely they are divided into cystids and polypides (e.g. Schwaha 2020). The cystids comprise the entirety of ...

If other bryozoan colonies are villages, cheilostomes form diverse cities. They have the regular complement of feeding zooids that gather food, but these are merely one type among a variety of ...The aptly-named magnificent bryozoan is especially large, and unlike other freshwater bryozoans, its colonies can create a jelly-like substrate to grow rather than having to individually cling to rocks. As zooids reproduce, they create darker-colored patterns on the surface of the substrate that make them look rather like strange stones.

At times, the colony can be comprised of a few to many millions of bryozoa, and in collective physical ...Bryozoan colonies also grow in many shapes, ranging from simple encrustations to little mounds to delicate vines and trees . Like convergence in shape between sharks and dolphins, similar growth forms have repeatedly and independently evolved, providing replicate examples for understanding their ecological significance.

Colonies are usually only a few inches across, but can grow to a foot wide or more in the right conditions. Bryozoan colonies attached to the underside of a pontoon boat pulled from Juno Lake, Cass County, Michigan. Bryozoans are harmless, tiny, filter-feeding aquatic invertebrates that can form jelly-like colonies on solid surfaces.

Much interest has focused on controlling bryozoan proliferation of inlet waters to farms, but the high level of infectivity of the innumerable spores released from relatively small colonies of bryozoans would mean that such control measures would have to be meticulously successful to confer protection to stock.

Extensive colonies of heavily calcified species may show indications of damage or instability. The flexibility of the substratum suggests that those species in ...Images of bryozoan colonies were also obtained through ROV video transects performed during the XXIX expedition, and subsequently identified at least to the genus level (Figure (Figure7). 7). Station coordinates and sampling events were recorded during sampling activities based on various GPS systems.The habitat was mostly deeply-rippled sand over a hard reef substrate at a depth of more than 50 m and a bottom temperature of 18° Celsius. Numerous large demosponges, gorgonians and hydroid cnidarians, erect fenestrate and foliose bryozoan colonies, and algae (including Caulerpa cf. longifolia) were present.tubular colonies with bean-shaped statoblasts that cannot float are in the family Fredericellidae.
