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

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.
