Bryozoans. Bryozoans (Phylum Bryozoa) are colonial, sessile animals that are usually encased in a protective covering with an opening for the animal's protruding tentacles. Each individual is very small and measures only several millimeters in length. They are usually found in marine environments, although some species are found in fresh water.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.The Bryozoa are the only animal phylum with an extensive fossil record that does not appear in Cambrian or late Precambrian rocks.
