bryozoan: [noun] any of a phylum (Bryozoa) of aquatic mostly marine invertebrate animals that reproduce by budding and usually form permanently attached branched or mossy colonies.Bryozoans. Introduction. The Bryozoa, also known as Ectoprocta or commonly as moss animals, are a phylum of aquatic invertebrate animals that resemble corals.

Bryozoans are microscopic aquatic invertebrates that live in colonies. The colonies of different species take different forms, building exoskeletons (outer protective structures) similar to those of corals. Most colonies are attached to a structure such as a rock or submerged branch. Freshwater bryozoans' exoskeletons are gelatinous (like jelly) or chitinous (like the "shells" of insects ...

The most successful terrestrial phylum and one of the most prominent freshwater taxa is Arthropoda. Its three subphyla with freshwater ...byrozoans (Bugula neritina) grown in elevated copper concentration were larger, dispersed farther and were tolerant of copper toxicity (Marshall 2008). Such maternal effects are likely to be greater in species with larvae that rarely leave the maternal habitat, such as those species that brood larvae. However, we foundAnd while zooids are small individuals on their own, colonies can be quite complex. Zooids within a single colony can come in different functions and morphologies – a bit like the organs in our bodies. This is known as zooid polymorphism and is associated with the division of labour within the colony.Lophotrochozoa: maps (42) Lophophorates lophophorates.

Bryozoans can be found in quiet lakes, ponds, streams and swamps attached to a surface under water. Pros and Cons of Bryozoans. Bryozoans are also a food source to fish, insects and snails. They also clean the water as they consume microorganisms. The presence of bryzoans typically indicates good water quality. bryozoans, emergent colony-level traits, such as the posi-tion and orientation of polymorphs relative to other zoo-ids in colonies, are known to have evolutionary potential (Simpson et al., 2020). While the sorting of aggregate traits has been subject to some prior study (e.g., Lloyd & Gould, 1993), the evolutionary potential of aggregate traits
