Bryozoans are a phylum of aquatic, sessile, colonial animals. These predominantly marine animals can be common, forming a conspicuous part of the hard substratum epifauna on most rocky shores, especially in shallow sub-littoral habitats. There are approximately 300 species in Britain.
This Synopsis covers the 36 species of the order Stenolaemata which occur in British waters. It is one of four Synopses devoted to the Bryozoa. The volume includes sections devoted to general bryozoan structure, the classification of Bryozoa and a key to the higher taxa.
