What are bryozoans
Bryozoans are zoologically unrelated to reef corals, of course, but their hard, calcareous crustose, mounded, and branching colonies superficially resemble those of cnidarians. Whereas in the tropics, bryozoans are mostly dwarfed by stony corals, in cooler temperate waters they come into their own, and can form bio-herms and mini-reefs.28 апр. 2022 г. ...

P. crispa mats ...Bryozoans often resemble seaweeds (or mosses) with which they are frequently confused by the public. 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.

Lophotrochozoa ( / ləˌfɒtroʊkoʊˈzoʊə /, "crest/wheel animals") is a clade of protostome animals within the Spiralia. The taxon was established as a monophyletic group based on molecular evidence. [2] [3] The clade includes animals like annelids, molluscs, bryozoans, brachiopods, and platyhelminthes. [4]Freshwater bryozoans are microscopic aquatic invertebrates that live in colonies that can form into jelly-like clumps, and are often found attached to docks or sticks.
