The objective of this study was to investigate decapod species occurring in the Turkish Straits System. For this purpose, benthic samples were collected from six different biotopes (photophilic algae, Cystoseira barbata, meadows, Posidonia oceanica, mussel, Mytilus galloprovincialis, meadows, Zostera marina, serpulid reef, and rocks) at depths ranging from 10 to 1000 m. A total of 60 species of decapod crustaceans were identified, including new records for the Turkish Straits System: Processa elegantula, P. modica, Richardina fredericii, Callianassa subterranea, Gourretia denticulata, Inachus parvirostris and Macropodia linaresi. In addition, some information about the spatial and bathymetric distribution as well as biotope preferences of the decapod community is provided.

This study deals with the presence of Mytilus galloprovincialis on the Mediterranean green crab, Carcinus aestuarii Nardo, 1847 as an epibiont. Crab samples were collected by means of single-entry fyke nets at 6 different locations selected in the Çardak Lagoon. A total of 22 specimens of M. galloprovincialis (1-9 ind. per crab) on different body parts of 4 crabs were recorded. This is the first report about the occurrence of M. galloprovincialis on C. aestuarii.

This study includes new records of soft corals found in the Turkish Straits System (Dardanelles) between 2013-2014. In the above-mentioned area, 50 stations were searched by scientific divers from the intertidal zone to a depth of over 45 m and the ecological characteristics with substrate differences were also recorded. A total of 47 cnidarians were examined during the surveys. Eleven anthozoan species (Aiptasia mutabilis, Alcyonium acaule, Andresia parthenopea, Calliactis parasitica, Cereus pedunculatus, Condylactis aurantiaca, Epizoanthus couchii, Maasella edwardsi, Pteroeides spinosum, Sarcodictyon roseum, Veretillum cynomorium) belonging to 4 orders are new to the Dardanelles strait, one of which is reported from the Marmara Sea. The current data contributed to the advancement of the knowledge about anthozoan species in the Turkish Seas.

The structure of the benthic amphipod assemblage and its relationship with soft-bottom characteristics (particle size, organic matter, etc.) of the coastal waters at the depths of 0-5 m at the Dardanelles, including the Turkish Straits System, was studied. A SCUBA diver took benthos and sediment samples seasonally using a quadrate system of 30×30 cm as three transects from the 8 different stations between July 2008 and April 2009. A total of 3007 individuals belonging to 50 species was reported. Among these, Corophium acutum Chevreux, 1908 had the highest dominance value (Di%=22.18) and the lowest dominance value belonged to Dexamine thea Boeck, 1861 (Di%=0.03). The highest positive correlation (rs=0.57, p<0.05) was observed between the gravel content (%) and the abundance (ind. m-2). The highest sand rate (99.59%) in the sediment was found at the Eceabat site. The lowest rate was at the Kepez Harbour station with a value of 73.01%. The highest H´ value (1.53) was recorded at the Eceabat site, and the lowest H´ value (H´=0.95) was recorded at the Gallipoli sampling station.

58 species of decapod crustacean were identified (1 Dendobranchiata, 14 Caridea, 5 Thalassinidea, 14 Anomura, 24 Brachyura) on soft substrates of the Aegean Sea coast of Turkey. Samples were collected from 60 sampling sites along the Turkish Aegean shore (eastern Aegean Sea) between July 2000 and September 2000 with dredge and a van Veen grab at bottom depths of 7 to 150 m. Different species dominated in each ecological zone with the anomuran squat lobster, Galathea intermedia Lilljeborg, 1851, being the most dominant species across the whole sampling area, comprising 11.71% of the individuals collected. This report represents the first published investigations into soft-sediment decapod communities in the coastal waters of the Turkish Aegean Sea.
