The ophiuroids collected from 13 localities in the vicinity of Cheiu Island during the period from July, 1965 to October, 1991 were observed for the systematic study on the basis of external features. As a result 26 species belonging to 11 families and 2 orders were identified, of which 5 species are neurly reported in Korean fauna and 6ey are as follows: Ophiomyxa austrolis, Ophioccnfho leuispino, Ophiactis dyscrita, Ophiocentws uenicillotus, Ophiorochnella infemolis. The ophiuroids distributed so far in Cheiu Island turned out to be 30 species.

Feeding ecology was compared among the three tonguefishes Cynoglossus abbreviatus, C. joyneri and C. robustus, collected from Seto Inland Sea, Japan, from June 2000 to May 2001. They are benthivores, consuming mainly gammarid amphipods, shrimps, crabs, gastropods, bivalves and ophiuroids. C. abbreviatus consumed greater proportions of ophiuroids whereas C. joyneri and C. robustus ate more amphipods and shrimps. While C. abbreviatus consumed mostly ophiuroids in all size classes, the diets of C. joyneri and C. robustus showed ontogenetic changes in feeding habits; smaller individuals of C. joyneri and C. robustus consumed gammarid amphipods, whereas larger C. joyneri ate shrimps and gastropods, and larger C. robustus fed mainly on gastropods, crabs, bivalves and polychaetes. Cluster analysis based on diet similarities emphasized that the three Cynoglossus species could be categorized on a size-related basis into three feeding groups: smaller C. joyneri and C. rubustus (<25 cm TL) could be classified as group A, and the larger of them (>25 cm TL) as group B, whereas C. abbreviatus was categorized as group C. This means that some degree of resource partitioning can occur among the three Cynoglossus species. The seasonal changes in the diets were also significant for the three Cynoglossus species.

Micronesia is an island nation located north of Papua New Guinea in the Pacific Ocean. A survey was executed on Kosrae, which is one of the four main islands of Micronesia, during January 23-30, 2011 and January 8-15, 2012. The echinoderms were collected at eight intertidal areas and at 12 SCUBA diving points at depths of 10-50 m in the subtidal zone. They were identified based on morphological characteristics. In total, 50 species from 276 individuals were identified: three crinoids, 11 asteroids, seven ophiuroids, 10 echinoids, and 19 holothuroids. Among them, two crinoids, five asteroids, three ophiuroids, four echinoids and two holothuroids were newly recorded from Kosrae.

Micronesia is an island nation located north of Papua New Guinea in the Pacific Ocean. A survey was conducted on Chuuk, which is one of the four main islands of Micronesia, from 11-25 Nov 2012. Echinoderms collected at one intertidal area as well as at 16 SCUBA diving points of 10-40 m depths in the subtidal zone were identified based on morphological characteristics. In total, 35 species from 165 individuals were identified: two crinoids, eight asteroids, four ophiuroids, seven echinoids, and 14 holothuroids. Among them, one asteroid, one ophiuroid, one echinoid, and two holothuroids were newly recorded from Micronesia.

Feeding habits of Limanda yokohamae collected from the eelgrass bed in Kwangyang Bay were studied. L. yokohamae (1-16 cm SL) was a carnivore which consumed mainly polychaetes. Its diets included a significant quantity of amphipods (gammarids and caprellids) as well as small quantities of gastropods and ophiuroids. L. yokohamae showed ontogenetic changes in feeding habits. Small individuals less than 4 cm SL preyed mainly on amphipods. However, polychaetes were heavily selected with increasing fish size while the portion of the diet attributable to amphipods decreased sharply. Polychaetes were the major prey organisms for all seasons. Dietary breadth of each size class shows relatively low value, and this means that L. yokohamae depends on only few kinds of food organisms.

Three new species of Collocheres are described as associates of crinoid and ophiuroid echinoderms from Cheju Island, Korea: Collocheres brevipes n. sp. from the crinoids Comanthus solaster A. H. Clark and Decametra tigrina (A. H. Clark); C. solidus n. sp. from two species of the crinoids Comanthus solaster and Comanthus japonicus (Muller) and one species of ophiuroid-Ophiomastax mixta (Lutken); and C. tamladus n. sp. from the crinoid Catoptometra rubroflava (A. H. Clack). The three species are distinguished from one another and other congeners by the body size, dimension of caudal ramus and free segment of leg 5, and shape and ornamentation of urosome.

The brittle star, Amphistigma minuta H.L. Clark, 1938, was collected from Munseom Island, Jeju-do, Korea, by SCUBA diving. This species has distinct morphological features, as follows: a small disk with large papillae on the disk margin; slender arms and four arm spines at proximal; and oral parts the same as those of the genus Amphipholis. Additionally, we obtained partial sequences of the cytochrome c oxidase subunit I gene (COI) (513 bp) and compared them with sequences from Australian A. minuta and 13 other species of Amphiuridae. As a result, intraspecific pairwise distance was 0.4% between two Korean individuals and intraspecific distance between the Australian and the Korean populations was 2.6-2.8%, which indicates they should be considered as the same species. Ultimately, 15 species of the family Amphiuridae have currently been recorded in Korea, including A. minuta.

등가시치의 식성을 조사하기 위해 가덕도 주변해역에서 1998년 3월부터 1999년 2월까지 채집된 등가시치의 위내용물을 분석하였다. 등가시치의 주요 먹이생물은 새우류 (Caridea), 옆새우류 (Gammaridea), 어류 (Pisces), 이매패류 (Bivalvia) 그리고 쿠마류 (Cumacea)였다. 그 외에 요각류 (Copepoda), 카프렐라류 (Caprel1idea), 패충류 (Ostracoda), 게류 (Brachyura), 두족류 (Cephalopoda), 복족류 (Gastropoda), 거미불가사리류 (Ophiuroidea) 및 갯지렁이류 (Polychaeta)가 위내용물 중 발견되었으나, 그 양은 많지 않았다. 등가시치가 성장함에 따라 먹이생물 조성에 있어서 변화를 보였는데, 작은 체장에서는 옆새우류, 이매패류 치패, 쿠마류 및 패충류 등 소형 먹이생물을 비교적 다양하게 섭취하였다. 그러나 성장하면서 소형 먹이생물들이 위내용물 중 차지하는 점유율이 급격히 낮아졌으며, 반면 새우류와 어류 등 비교적 큰 먹이생물의 점유율이 크게 증가하였다.

통영주변해역에서 2010년 1월부터 12월까지 문치가자미 395개체를 채집하여 위내용물을 분석하였다. 채집된 개체는 표준체장 10.5~38.8 cm의 체장범위를 나타내었다. 문치가자미는 저서성 육식어류로써 주로 이매패류, 단각류, 갯지렁이류를 섭식하였고, 그 외 약간의 유형동물류, 산호충류, 등각류, 요각류, 주걱벌레붙이류, 새우류, 게류, 거미불가사리류를 섭식하였다. 문치가자미는 generalized feeder의 섭식전략을 나타냈고, 체장이 커짐에 따른 주 먹이생물의 변화는 나타내지 않았으며, 먹이생물의 크기변화는 나타나지 않았다.

통영주변해역에서 2010년 1월부터 8월까지 낚시, 자망 그리고 새우조망을 이용하여 돌가자미 102개체와 줄가자미 101개체를 채집하고 위내용물을 분석하였다. 각각의 위내용물 분석 결과 돌가자미는 이매패류와 어류가 대부분을 차지하였고, 줄가자미는 거미불가사리류가 위내용물의 대부분을 차지하여 저서성 육식어류로 나타났다. Prey-specific abundance 분석 결과 다른 가자미과 어류들과 비교하여 깊은 수심에 서식하는 돌가자미와 줄가자미는 각각 이매패류와 거미불가사리류에 섭식이 특화된 specialist predator로 나타났다. 돌가자미와 줄가자미는 같은 지역에 출현하는 유사종 사이에서 나타날 수 있는 먹이경쟁을 피하기 위해 서로 다른 식성을 가지는 것으로 판단할 수 있다.
