Alone among lophophorates, Bryozoa includes freshwater representatives. The lophophore may be circular or horseshoe shaped in cross section. A small epistome may be present anterior to the mouth. Pages for logged out editors learn more Conclusions. We are able to show distinct similarities among bryozoans in the formation of the different organ systems: a two-layered vesicle-like early bud, the ganglion forming as an invagination of the epidermal layer in between the prospective mouth and anal area, the digestive tract mainly forming as an outpocketing of the prospective anal area, and the lophophore forming from two lateral ...
1 Anatomy. Bryozoa is a phylum of usually sedentary colonial marine invertebrates. Colony morphologies are diverse, typically encrusting or branching, many of them calcified. In all species, the majority or totality of the colony is composed of (typically) box- or cylinder-shaped “autozooids,” which feed, providing nourishment for the colony.

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 ...

Cristatella mucedo, Cuvier 1798, is a characteristic worm-shaped and mobile colony of freshwater bryozoans. It is the sole representative of the genus Cristatella and sole species of the family Cristatellidae. It is commonly found on plants or other substrates in ponds or other freshwater habitats. bryozoans have this kind of feeding current, and it apparently was the way that the Paleozoic fenestrates (Figure 6) handled the water from which they fed.
