Protoperidinium spp. are heterotrophic dinoflagellates in the world ocean. Although most Protoperidinium species are known to feed on diatoms and bacteria, several species feed on red tide dinoflagellate. The samples were collected from 17 locations in the neritic areas of Korea from 1990 to 2010. In the thecate dinoflagellates, the thecal plate pattern has been considered to be important criteria in their classifications. Thecate dinoflagellates with distinct epitheca and hypotheca separated by a girdle which is usually equatorial and may or may not be displaced with or without overhang. Due to this fact the shape of the theca and the arrangement of the theca were studied. The shape of first apical plate is considered an important factor. To identify the genus Protoperidinium, the shape of the first apical plate and the second anterior intercalary plate were used. Depending the shape of first apical plate, will be designated as meta(4), meta(5), para(4), para(5) or para(6). From this point of view, the genus Protoperidinium as a group of planktonic protist in the coastal area was classified.
