Some forty species of scleractinian corals live in a particular, very muddy, environmment situated in the South-Western lagoon of New Caledonia between 25 and 30 metres depth. The seabed is caracterised by the topography of ridges valleys and bumps and appears to be formed of accumulated molluscs shells, scleractinian skeletons and fine particles. The presence on the soft bottom of these various hard substrata allows the scleractinian larvae to establish themselves. In order to survive, these corals have developed various growth strategies which are designed to offset some unfavourable factors such as hypersedimentation and the species sinking they become heavier as they grow. The majority of the corals found on this site are species with well-developed polyps that are able to reject sedimentary particles. The other species survive by growing, probably very rapidly, vertically or horizontally, or else by increasing their area of contact with the sediment accompanied by an abundant secretion of mucus
