Water Flow in the Ecology of Benthic CnidariaThe following four papers were given in a special session of the Third International Symposium on Coelenterate Biology. They present some principles of water flow and the possible reactions of bodies to flow, and then apply them to studies of feeding and survival of certain benthic cnidarians.

Competitive Interactions and the Species Diversity of Coralsals such as sponges, corals, etc., competition for space is obviously an important factor. On a small area of hard substrate with very little spatial variation in local physical conditions, one might expect that a single species would be superior to all others in competition and would eliminate them and eventually cover the surface.

Habitat-Related Patterns of Productivity of the Foliaceous Reef Coral, , Dana is capable of tentacular feeding and other heterotrophic activities (Goreau, .., 1971; Muscatine, 1973; Trench, 1974; Porter, 1974; Muscatine and Porter, 1976). Many workers have examined the photosynthesis of reef corals (McCloskey, .., 1976) but habitat acclimation has generally been ignored.

Regulation of Feequency of Pedal Laceration in a Sea Anemonedal laceration consists of a radial spreading of the pedal disc followed by the separation of a more or less complete ring of tissue derived from the peripheral margin of the disc. This ring subsequently fragments into two to eight pieces of tissue, each of which develops in about two weeks into a small anemone capable of feeding.

The Acrorhagial Response in , I: Intraspecific and Interspecific Recognitioning atrich nematocysts (usually some basitrich nematocysts and spirocysts present), which have been considered a major characteristic of acrorhagi (Carlgren, 1949; Abel, 1954; Bonnin, 1964; and Francis, 1973b).
