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.Bryozoa [edit | edit source] A freshwater Bryozoan, species unknown.

Bryozoans Often referred to as moss animals, Bryozoans are filter feeders that sieve food particles from the water using a crown of cilia-lined tentacles. Most dwell in moist environments, from temperate waters to glacial regions and even marine trenches. Bryozoan colonies consist of zooids, individual yet interdependent entities. VertebratesWhat are bryozoans? Bryozoa is a large phylum in the animal kingdom, which is made up of around 6,500 living species. All species live in water, with most inhabiting the oceans.. Each colony is made up of many individual zooids, which are small invertebrate animals less than a millimetre in length and genetically identical.Bryozoans are a distinct group of water-dwelling, filter-feeding animals.
