BRYOZOA (POLYZOA, ECTOPROCTA)
Bryozoans are minute sessile colonial animals. There are two marine classes (Stenolaemata and Gymnolaemata). Gainey, in Spalding, A., (Ed) 1997, has previously reviewed the status of the marine bryozoans in Cornwall. There is no Red Data Book for these species and the following account is based on the author’s experience of the marine environment in Cornwall and Scilly and also Hayward (1985), Hayward & Ryland (1979 and 1985) and Ryland & Hayward (1977). 21 species have been listed here as pRDB or pNS to indicate that they would probably be considered for inclusion in a national book of RDB or NS species.
