The phylum comprises ~6000 living species [] which grow into a bewildering array of colony types, including soft (weedy or gelatinous) and hard (calcified) forms, which may be moss-, sponge-, or coral-like in overall appearance. Bryozoans (Ordovician to today with no peak period) are animals that live in a colony and excrete a skeleton to support themselves. Sometimes the skeleton is made of minerals, and sometimes it is made of chitin. Bryozoans are primarily marine, but are sometimes found in tidal or delta environments.
