filaments into a cavity it formed with its body wall to digest entrapped food items. Miles (1991) reported that the Caribbean corallimorph Discosorna sanctitbomae would extrude mesenterial filaments from the mouth and through the body wall upon initial contact with other anthozoans. In addition, both species could transfer mesenterial filaments to, and out of, the tips of the distal tentacles. So it is possible that other corallimorphs have similar abilities and the aquarist should take this into consideration when placing corallimorphs near other corals.
