Abstract

Juveniles of the tube-dwelling polychaete L. conchilega were found attached to adult tubes at an exposed beachin South Wales (U.K.). They attached to the upper part of tubes protruding above the sediment. The aim of thisstudy was to determine the timing of juvenile settlement on to adult tubes, thei...
