Abstract Samples were taken by diver-held corer at Lizard I., northern Great Barrier Reef, to investigate community organization and to relate community and sedimentary variables. Cluster analysis grouped the finest-sediment sites together and isolated a single mangrove site. Other site-groupings were more heterogeneous and supplementary analyses supported an individualistic continuum interpretation. Sites were also classified with respect to sediments. The finest-sediment site-group had significantly fewer species than coarser site-groups and a significant correlation existed between species richness and median phi. Species richness and evenness were positively related but the more variable sediments did not support more species. No relationship between number of individuals and sediments was apparent.
