Benthic Polychaetous Community in Youngil Bay, Southeastern Coast of Korea

This study was carried out to investigate the benthic polychaetous community in the Youngil Bay, at July in 1993. Polychaetes, the dominant faunal group occupying 78.2% in the total faunal density, comprised a total of 42 species with a mean density of 526 indiv.m⁻². The number of species and density were higher in the southeastern area of Youngil Bay. This area had also higher species diversity. The dominant polychaete was Lumberineris longifolia(18.0% ), followed by Spiophanes bombyx (12.5%), and Nephtys polybranchia(11.3%). The cluster analysis revealed that the study area could be divided into two regions, the area of Hyoungsan River Mouth and the other area.
