  • Two species of the family Porcellidiidae associated with hermit crabs are described from Korean seas. These are Porcellidium similis, new species collected from Pagurus similis, Pagurus pectinatus and Porcellidium brevicaudatum Kicks & Webber collected from Dardanus impressus. The new species resemble closely Porcellidium brevicaudatum in general body form, but is clearly distinguished from Porcellidium vrevicaudatum in that the caudal ramus is weakly oblique in tis distal border and the lobe of leg 5 is more slender.

  • This study reports the pagurid hermit crab Porcellanopagurus japonicus in Korean waters for the first time. This species has a right cheliped larger than the left one, reduced and globular abdomen, and symmetrical uropods. Porcellanopagurus japonicus is similar to P. nihonkaiensis, a previously reported congeneric species in Korea, but also has distinguished morphological and ecological characters. There are currently issues with the Korean scientific name for P. japonicus, we suggest a reasonable Korean scientific name of this organism with its etymology. In addition, this species inhabits bivalve shells, which is not a typical habitat for hermit crabs, and the unique habitats of this and several other Korean hermit crabs are reviewed.

  • 한국 동해안에서 채집된 2종의 집게류가 검은털손참집게 (Pagurus proximus)와 갈색털손참집게 (Pagurus simulans)로 동정되었으며, 처음으로 한국에서 확인되어 보고한다. 2종은 그 동안 모두 털손참집게 (P. brachiomastus)로 인식되어오던 종으로, 최근 Komai (2000a)에 의해 이들 분류학적 관계가 재정립되었다. Komai (2000a)에 의하여, 한국에서 김 (1973)이 털손참집게로 보고한 종은 검은털손참집게의 동종이명으로 처리되었으며, 본 연구를 통하여 재확인되었다. 한편 갈색털손참집게는 한국에서는 처음으로 보고되는 종이다.

  • 2004년 1월부터 12월까지 부산 주변해역에서 채집된 참돔의 식성을 조사하였다. 참돔의 체장분포는 8.5~44.6 cm SL의 범위였다. 참돔의 주요 먹이생물은 집게류 (Anomura), 단각류 (Amphipoda), 게류 (Brachyura), 새우류 (Caridea), 갯지렁이류 (Polychaeta), 극피동물 (Echinodermata), 어류(Pisces) 등 매우 다양했다. 그 외, 복족류(Gastropoda), 이매패류(Bivalvia), 갯가재류(Stomatopoda), 두족류(Cephalopoda) 자포동물(Cnidaria), 등각류(Isopoda) 등도 소량 섭이하였다. 참돔은 성장함에 따라 먹이생물 조성에 있어 변화를 보였는데, 체장 8~15 cm SL에서 새우류의 점유율이 높았으며, 15~25 cm SL에서는 집게류와 갯지렁이류의 점유율이 높았다. 그리고 25 cm SL 이상에서는 극피동물류와 어류의 점유율이 높게 나타났다.

  • Pagurus undosus and Pagurus parvispina, collected from the East Sea by fishery trap, are newly recorded from Korean waters. Pagurus undosus is distinguished from other hermit crab by its right cheliped slightly elevated medially, and with broad ridge formed by deep depressions mesial and lateral to midline. Pagurus parvispina is distinguished from other hermit crab by its right cheliped covered with large spine and long tufts of setae. These species live in cold water areas and their geographical distribution is extended southwardly by the present study. A specimen of the former species, P. undosus, was found living in a shelter formed by a sponge, similar to that observed in Pagurus pectinatus. Descriptions and figures of these two species are provided in this paper. Currently, 27 species of the genus Pagurus are recorded in Korean fauna.

  • Two diogenid hermit crab species, Dardanus lagopodes and Diogenes deflectomanus, are newly reported from Korea. Dardanus lagopodes is distinguished from the other species of genus Dardanus in Korea by having setae with cream-colored tips on the cephalothorax and the following characteristics: ocular peduncles somewhat longer than antennular peduncles, and the pereopod without a longitudinal sulcus and scute-like projections. Diogenes deflectomanus is similar to D. nitidimanus but can be distinguished by having the fixed finger of the left cheliped bent slightly downwardly and the following characteristics: slightly shorter ocular peduncle, elongated left cheliped with small granules on the surface, right cheliped without calcareous teeth on the cutting edge of the dactylus, and the minute spine of post-median margin of the telson is not well developed. The geographical distributions of these two species are extended by the present study. In particular, D. deflectomanus in the current study is the first report outside Chinese waters. Now, 20 species of the family Diogenidae are known in Korean waters.

  • The feeding habits of Hoplobrotula armata were studied using 269 specimens collected in the coastal waters of Geomun-do, Korea. The size of the specimens ranged from 5.6-56.8 cm in total length (TL). H. armata is a canivore that consumes mainly teleosts and decapods (shrimp, crabs and hermit crabs). Its diet also includes gammarid amphipods, cephalopods, polychaetes and copepods. Smaller individuals (<20 cm TL) fed mainly on fish, shrimp and crabs. The proportion of shrimp and crabs decreased as body size increased, whereas the consumption of fish gradually increased. Fish accounted for almost the entire stomach contents of individuals (larger than 40 cm TL).

  • 경남 통영 연안해역에서 채집된 쏨뱅이(Sebastiscus marmoratus) 324개체의 식성을 조사하였다. 쏨뱅이의 표준체장(SL)은 9.8~30.1 cm 범위였다. 쏨뱅이의 위 내용물을 분석한 결과 쏨뱅이는 멸치(Engraulis japonicus), 청어(Clupea pallasii), 망둑어류(Gobiidae)와 같은 어류(Pisces)를 주로 섭식하는 어식성어류였으며, 어류 중에서 멸치를 가장 선호하였다. 어류 다음으로 새우류(Macrura)와 게류(Brachyura)를 섭식하였으며, 그 외에 집게류(Anomura), 갯지렁이류(Polychaete), 이매패류(Bivalvia), 난바다곤쟁이류(Euphausiacea)를 섭식하였지만 그 양은 많지 않았다. 체장이 16 cm 이하의 개체는 새우류와 게류를 주로 섭식하였다. 새우류와 게류의 비율은 체장 증가에 따라 감소한 반면, 어류의 비율은 점점 증가하였다. 어류는 체장 19 cm 이상의 개체에서는 위 내용물 중 대부분을 차지하였다. 쏨뱅이의 위 내용물을 계절에 따라 유의하게 변하였다. 어류는 여름, 가을, 겨울에 중요한 먹이생물인 반면 게류와 새우류는 봄에 주로 섭식되었다.

  • The seasonal and interannual variation in the species composition and abundance of the decapod assemblage (shrimps, crabs, and hermit crabs) collected using pots in the coastal waters off Gori were studied between 2005 and 2008. During the study period, 49 decapod species belonging to 19 families were collected. The dominant species were Crangon hakodatei, Pandalus gracilis, Carcinoplax longimana, Charybdis bimaculata, Carcinoplax vestita, Diogenes edwardsii, and Dardanus arrosor. These seven species accounted for 95.46% of the total number of individuals collected. The number of species, number of individuals, biomass, and species diversity indices fluctuated with the seasons. The peak number and biomass of individuals occurred in July 2006. The number and biomass of individuals were higher in summer and lower in winter, and the diversity indices were lower in summer than in the other seasons. The abundance of dominant species showed some seasonal and interannual change; in particular, those of C. hakodatei and P. gracilis corresponded with the bottom water temperature.
