The composition and the assemblage structure of the molluscan fauna along a depth gradient from the infralittoral hard bottom photophilic algae communities in the Cretan Sea, East Mediterranean, was studied at 2 different sites during the summers of 2007 and 2008. Samples were collected by means of SCUBA diving under the NAGISA project protocol. Examination of the material revealed 129 species,...
