| Abstract |
The beach of Pléneuf-Val-André (Brittany, France) is rich in disarticulated shells encrusted by bryozoans. This study revealed a bryozoan fauna typical of nearshore conditions in water between 5 m and 50 m deep. The hydrodynamically most stable position (convex side up) is not equally exhibited by the different species of shell and relatively large numbers of shells have the concave side uppermost. A total of 55 species of Bryozoa were encountered: five ctenostomes, seven cyclostomes and 43 species of Cheilostomata were identified. Larval recruitment, time of colonisation and the most common encrusting species are discussed. Species of special interest are an aberrant form of Microporella ciliata and the rare Ellisina gautieri and Escharoides bishopi. Distansescharella seguenzai is reported for the first time on both sides of the English Channel and from the Thames area of the United Kingdom. |
