Bryozoa (bryozoans) are aquatic colonial animals, which are abundant in modern marine environments, and have been important components of the fossil record since the Ordovician. In places, the skeletal remains are so abundant that the fossils become an important rock-forming material. Common vernacular names include 'sea mats', 'moss animals' or 'lace corals'. The majority are marine, although brackish-water and freshwater forms are fairly common. Please follow the links below, to find out more about bryozoans.
