In order to reveal the taxonomic composition and the species distribution of periphytic ciliates in Korean coastal waters, a three-month survey was carried out using glass slides as artificial substrates at two depths (1 and 2 m) in the coastal area of Incheon, Korea, from August to November 2007. A total of 40 ciliates with twelve dominant species, about half of which belonged to the orders Hypotrichida and Cyrtophorida, were identified by in vivo observation and silver impregnation method. The sessile ciliates were represented by the species of the orders Peritrichida and Suctorida, and the motile forms belonged primarily to the orders Hypotrichida, Cyrtophorida and Pleurostomatida. The peritrich Zoothamnium spp. and the heterotrich Folliculinopsis producta were the most dominant species in the samples from the both depths, but appeared more predominating at the lower depth. Multivariate analysis showed that the species distribution was considerably different between the two sampling depths mainly due to 12 dominant species, which had different abundance and occurrence. Our results suggest that for detecting the temporal and spatial dynamics of ciliate communities it is necessary to position the colonizing depths in marine ecosystems.
