This study took place between March 1981 and September 1982. Observations and experiments involved A. agaricites and various sessile animals spanning a range of competitive strategies and including four corals, a zooanthid, and a gorgonian (Table I). Among the stony corals used, A. agaricites can digest two species (Madracis decactis [Lyman] and Porites astreoides Lesueur) and can be digested by the two other species (Montastraea annularis [Ellis and Solander] and Montastraea cavernosa} (Lang, 1973). Within each pair of digestively dominant or subordinate corals, one can sometimes possess sweeper tentacles (Madracis decactis, pers. obs.; M. cavernosa, Lewis and Price 1975) while the other doe not (P. astreoides and M. annularis} (Table I). The zooanthid Palythoa caribbea D^chassaing and the gorgonian Erythropodium caribaeorum Duchassaing and Michelotti sometimes overgrow Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
