Abstract |
The anomuran species known from Korean waters are 57 species in 12 families: Axiidae (1 sp.), Laomediidae (1), Callianassidae (1), Upogebidae (1), Pomatochelidae (1), Diogenidae (12), Paguridae (19), Lithodidae (6), Chirostylidae (2), Galatheidae (4), Porcellanidae (7) and Albuneidae (2); and brachurans are 183 sp.in 20 families: Dromiidae (6), Tyomlidae (1), Latreillidae (2), Raninidae (2), Dorippidae (2) Calappidae (9), Leucosiidae (12), Majidae (33), Hymenosomatidae (5), Parthenopidae (4), Atelecyclidae (4), Cancridae (3), Corystidae (1), Purtunidae (16), Goneplacidae (5), Hexapodidae (1), Xanthidae (22), Grapsidae (29), Pinnotheridae (10) and Ocypodidae (16).The author divided the coastal waters of Korea into 4 regions: the Japan Sea (JS), the Korea Strait (KS), the Cheju Island waters (CI), and the Yellow Sea (YS), dividing those animal species into 3 geographical distribution forms: northern form (N), temperate zone form (T) and southern form (S).The anomuran species consist of 9N, 40T and 8S; and brachyurans consist of 7N, 87T and 89S.In anomuran case 29 sp.(9N, 19T, 1S), 30 sp.(2N, 24T, 4S), 30 sp.(0N, 24T, 6S) and 21 sp.(2N, 17T, 2S) appeared in JS, KS, CI and YS respectively, and in brachyuran case 62 sp.(7N, 32T, 23S), 121 sp.(1N, 66T, 54S), 104 sp.(1N, 39T, 64S) and 74 sp.(1N, 46T, 27S) ditto.In anomuran case 8 sp.(6N, 2T, 0S), 3 sp.(0N, 2T, 1S), 16 sp.(0N, 12T, 4S) and none occurred in only JS.KS, CI and YS respectively.In brachyuran case 8 sp.(6N, 1T, 1S), 20 sp.(0N, 14T, 6S), 40 sp.(0N, 10T, 30S) and 12 sp.(0N, 9T, 3S) ditto.7 of 57 anomuran species and 23 of 183 brachyuran ones were found in all 4 regions.Similarity coefficients of species composition between two of 4 regions were calculated.Environmental conditions of those regions were mentioned for understanding distributional aspects of the animals |
