Introduction to the Bryozoa
For More Information: http://bryozoa.net/bryointr.html

"Bryozoa are aquatic colonial animals, which are abundant in modern marine environments, and have been important components of the fossil record. In places, the skeletal remains are so abundant that the fossils become an important rock-forming material. If you need a common name, then you can call them 'sea mats', 'moss animals' or 'lace corals' for some forms. The majority are marine, although brackish-water and freshwater forms are moderately common."
