Diversity and New Records of Polychaetes (Annelida) in the Sinop Peninsula, Turkey (Southern Black Sea)

Objectives: This study determines the diversity of annelid polychaete species distributed around the coast of Sinop and to identify possible spatial and temporal variations of the Polychaeta community. Material and Methods: Benthic material was collected from 8 stations using Van Veen grab between October 2013 and July 2014 on the soft bottom of Sinop Peninsula. Results: A total of 90 species belonging to 30 families were identified. Among them, Galathowenia cf. oculata, Rhodine loveni Malmgren, 1865, Paradoneis armata Glémarec, 1966, Paralacydonia paradoxa Fauvel, 1913 and Syllis cf. amica are new records for the Black Sea fauna and Glycera tridactyla Schmarda, 1861 is new for the Turkish coast of the Black Sea. Prionospio (Minuspio) maciolekae Dagli and Çinar, 2011, Micronephthys longicornis (Perejaslavtseva, 1891) and Protodorvillea kefersteini (McIntosh, 1869) were the most frequent and dominant species in the study area. The highest mean number of species (29 species) was found in spring at station G2; the lowest mean number of species (4 species) was determined at station G3 in winter. The highest mean density value (9470 ind. m-2) was determined at G2 station in summer; the lowest mean density value (357 ind. m-2) was calculated in autumn at station G5. Conclusion: The Polychaeta diversity on the soft bottom of the Sinop Peninsula was analyzed and four species were newly recorded for the Black Sea fauna and one for the Turkish Black Sea fauna.
