International Biodeterioration and Biodegradation, 2017, 120, 97–103. Article Google ScholarBryozoans are tiny animals, no larger than 4 millimeters (5/32 of an inch) wide. They float alone for a time, but eventually form colonies, working together for mutual benefit. In this way, they are much like coral. But coral builds strong, sturdy structures that last long after the animals they house have died.

Bryozoa. Bryozoans, also known as the Polyzoa, Ectoprocta or moss animals, are a phylum of small aquatic animals living in colonies. The colonies usually have a skeleton of calcium carbonate.
