Abstract

Bivalve assemblages on coral carpets in the Northern Bay of Safaga donot form distinct associations, but gradually shift in faunal composition. The taxonomic shift is accompanied by continuous variations in bivalve density and percentage of living individuals as well as by a change of coral associations and potential bivalve habitats. The graduallateral change of associations is best documented by Tridacna maxima and jewel box clams (Chamoidea) and is probably due to variations of the suspension load in the water column. High suspension loads in the water column are additionally indicated by 'giant oysters' (extremely large individuals of Hyotissa hyotis) and striking agglomerates of Lopha cristagalli. The vertical differentiation is best documented by the decrease of the zooxanthellate Tridacna maxima and is probably due to the depth-dependent light penetration in the water column, which is attenuated in areas of high suspension load.
