    (Central Fisheries Research Inst, 2015) Dagli, Ertan; Sahin, Guley Kurt; Sezgin, Murat; Cengiz, Zeynep
    The present paper deals with ecological and morphometric features of Ophelia bicornis Savigny in Lamarck, 1818 collected monthly from the Sinop Peninsula (Black Sea, Turkey) between August 2009 and July 2010 from 4 stations. This study aimed to report the polychaete for the first time from the Turkish coast of the Black Sea and to determine the population density of O. bicornis on the coasts of the Sinop Peninsula. A total of 699 individuals of O. bicornis were collected. The maximum and minimum density was counted at station A in autumn (October, November, respectively). The female individuals of O. bicornis were recorded between May and October. The regression formula for the length (mm)-weight (g) relationship was found to be W=0.0002xTL(2.11), indicating that the growth for O. bicornis is allometric. The statistically significant correlation between percentages of coarse sand and number of individuals and biomass of O. bicornis were estimated.

    Marphysa cinari, a new species of Eunicidae (Polychaeta) from the coasts of Turkey (eastern Mediterranean) and re-descriptions of Marphysa kinbergi McIntosh, 1910 and Marphysa disjuncta Hartman, 1961
    (Taylor & Francis Ltd, 2014) Sahin, Guley Kurt
    The present study describes a new polychaete species belonging to the family Eunicidae, Marphysa cinari sp. nov., collected from the Sea of Marmara and the Aegean Sea (eastern Mediterranean), and re-describes Marphysa disjuncta Hartman, 1961 and Marphysa kinbergi McIntosh, 1910. The new species is mainly characterized by having unidentate subacicular hooks with a terminal hood and compound falciger chaetae on posterior parapodia. The shape of unidentate hooks of M. cinari is a very important character for distinguishing this species from other species. Atlantic species M. kinbergi and Pacific species M. disjuncta are very close species and the present paper deals with the differences and similarities between them and the new taxon. http://zoobank.org/urn:lsid:zoobank.org:pub:E8503032-81D3-4B4D-AAA-09164E05E613F
