Özet

The present study deals with the mollusc species, except for Solenogastres, Bivalvia and Cephalopoda, sampled from the soft substrata of the Sea of Marmara in 2013. The benthic material was collected at 50 sampling sites in different depths (10 m, 25 m, 50 m, 100 m and 200 m) using a Box Core sampler. As a result of the faunistic analysis of the benthic material, a total of 210 species and 22244 individuals belonging to the identified taxa were counted. Ondina dilucida (Monterosato, 1884) is a new record for the mollusc fauna of Turkiye, and 19 species [Ischnochiton rissoi (Payraudeau, 1826), Sinezona cingulata (O.G. Costa, 1861), Cerithiopsis diadema Monterosato, 1874, Melanella levantina (Oliverio, Buzzurro & Villa, 1994), Setia fusca (Philippi, 1844), Setia turriculata Monterosato, 1844, Granulina occulta (Monterosato, 1869), Liostomia clavula (Lovén, 1846), Odostomia angusta Jeffreys, 1867, Ondina diaphana (Jeffreys, 1848), Parthenina dollfusi (Kobelt, 1903), Parthenina juliae (de Folin, 1872), Parthenina palazzii (Micali, 1984), Turbonilla gradata Bucquoy, Dautzenberg & Dollfus, 1883, Turbonilla hamata Nordsieck, 1972, Turbonilla pumila Seguenza, G., 1876, Acteon monterosatoi Dautzenberg, 1889, Antalis panorma (Chenu, 1843), Dischides politus (S. Wood, 1842)] are new reports to the faunistic inventory of the Sea of Marmara. The most dominant species were Bittium reticulatum (da Costa, 1778) (59.1%; total of 13147 ind.) and Megastomia conoidea (Brocchi, 1814) (3.4%; total of 747 ind.). Besides, Bittium reticulatum and Hyala vitrea (Montagu, 1803) had the highest frequency values (37.1% and 28.7%) in the area.
