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=0.0002×TL2.11, indicating that the growth for O. bicornisis allometric. The statistically significant correlation between percentages of coarse sand and number of individuals and biomass of O. bicornis were estimated.
