The species composition and variation of benthic marine algae at Daejin and Jukbyeon on the mid-east coast of Korea were investigated seasonally from August 2006 to April 2007. As a result, the total of 85 species, including 8 chlorophytes, 26 phaeophytes, 50 rhodophytes and 1 sea grass were identified. 52 species were found at Daejin and 74 species at Jukbyeon. Dominant species in importance value were Corallina pilulifera, Chondrus ocellatus, melobesioidean algae, Sargassum horneri, Sargassum yezoense and Phyllospadix japonica at Daejin, and Corallina pilulifera, melobesioidean algae, Phyllospadix japonica, Acrosorium polyneurum, Sargassum siliquastrum and Hizikia fusiformis at Jukbyeon, respectively. The vertical distribution of algae were characterized by Corallina pilulifera, Hizikia fusiformis, Sargassum spp. (S. siliquastrum, S. yezoense) and Symphyocladia latiuscula at intertidal zone, Sargassum spp. (S. horneri, S. serratifolium, S. yezoense), melobesioidean algae, Phyllospadix japonica and Corallina pilulifera at 1 m depth, melobesioidean algae, Phyllospadix japonica and Sargassum spp. (S. horneri, S. yezoense) at 5 m depth and melobesioidean algae, Phyllospadix japonica and Sargassum spp. (S. horneri, S. micracanthum, S. yezoense) at 10 m depth.
