Abstract : The Discovery Bay Marine Laboratory, its location, facilities, equipment and staffing, is described. The reefs of the study area, of the fringing type, are very close to shore, generally steep, and with an exceedingly rich fauna and flora which is easily accessible by diving from small boats. A total of 71 species of shallow water scleractinian corals, including 53 reef-builders and 18 non-reef-builders are being studied. Behavioural interactions between corals to be of considerable taxonomic and ecologic importance. Extensive submarine lithification was found to occur in Jamaican north coast reefs, at apparently all depths. Seven species of silico-calcareous coralline sponges are being described. To accommodate these organisms it was necessary to erect a new Class in the Phylum Porifera, the Sclerospongia. They appear to be modern descendents of Stromatoporoids. Investigations of calcareous algae have centred mainly on the genus Halimeda and its role in reef sedimentation.
