A systematic study on the Errantiate Polychaeta in Cheju Island.
[English abstract:]
The specimens of the errant polychaetes collected from ten localities in Cheju Island during 1969 to 1987 are identified into 31 species in 9 families. The total number of the errant polychaetous species which include the previous records and the present materials in Cheju Island are 45 species in 11 families. Among them, 4 species (Lepidasthenia berkeleyae, Brania clavata, Sphaerosyllis hirsuta and Ceratonereis singularis) are newly known from Korean waters and the description and figures of these 4 species are given. Of 45 species, 13 species are reported only in Cheju Isand. Twenty-two (48.89%) species of 45 are warm-temperature form, 10 species (22.22%) cosmopolitan form, 8 species (17.78%) tropical form, 4 species (8.89%) cold temperature form, and 1 species (2.22%) boreal form. This is in accord with the environmental factor that Cheju Island is strongly influenced by Kurushio Warm Current.
