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 ... Bryozoans, also known as Ectoprocta, and commonly referred to as moss animals (bryophytes are mosses) have been around since the Cambrian.
