  • A sea star was collected with fishing nets at a depth of approximately 100-160 m in the East Sea and was identified as Stephanasterias albula (Stimpson, 1853) belonging to the family Asteriidae of the order Forcipulatida. This species characterized by having the capability of asexual reproduction by self-division turned out to be new to the Korean fauna. Its morphological characteristics are redescribed with illustrations. Thirty one species of sea stars including S. albula are now recorded from the East Sea of Korea.

  • Some sea stars were collected from the coast of Seogwipo, Jejudo Island by using the fishing net at April 2003, and were identified on the basis of their morphological characteristics. Among them, Paragonaster ctenopes Sladen, 1889 belonging to family Goniasteridae, order Phanerozonia is newly recorded from Korea. Twenty two species of asteroids are reported to be distributed in the Jejudo Island of Korea.

  • 1980년 4월부터 1992년 4월까지 우리나라의 남해연안과 여러 도서 지방의 총 69개 지역에서 채집된 해성류를 동정하였다. 그 결과 5목 8과 23종이 밝혀졌고, 이들 중 Mediaster brachiatus와 Stellaster equestris 2종은 한국 미기록종이었으며 Asterina pecitinifera는 43개 지역에서 채집되어 가장 흔한 종이었다. 대한해협과 제주도 해역에는 각각 15종의 해성류가 있었으며 온대종 15종, 열대종 7종, 한대종 3종이 분포하고 있었다. 현재까지 밝혀진 해성류는 43종이 된다.

  • Sea stars were collected with fishing nets between depths of 40-150 m from the Gangwon-do coastal region, East Sea. Specimens were identified as Evasterias echinosoma Fisher, 1926 belonging to the family Asteriidae, which is new to the Korean fauna. This species was characterized by strong external spines and a general size of more than 200 mm, thus the largest sea star identified in Korea to date. Its morphological characteristics are described here with photos. Thirty two asteroid species including E. echinosoma have been reported from the East Sea of Korea.

  • Henricia specimens were collected using fishing nets from 14 November 2012 to 8 June 2018 from the East Sea of Korea. The specimens were identified as Henricia sanguinolenta (O.F. $M{\ddot{u}}ller$, 1776), belonging to the family Echinasteridae of the order Spinulosida, which is known for its wide distribution throughout the world. This species can be distinguished from other Henricia species by long arms (R/r=6-6.8), thick arm base, coarser stubby abactinal spines with more than ten apical points, and visible longitudinal series of actinal ossicles. Previously, eight species of the genus Henricia were reported in the Korean fauna. The morphological characteristics of this species were prepared and described with illustrations.

  • 1990년 4월부터 1993년 8월까지 우리나라의 동해 연안의 총 36개 지역에서 채집된 해성류를 동정하였다. 그 결과 5목 8과 19속 29종이 밝혀졌고, 이들 중 Solaster endeca, Lethasterias fusca, Lethasterias nanimensis chelifera, Lysastrosoma anthostictha, Evasterias troscheli alveolata 등 5종은 한국 미기록종이었다. Asterina pectinifera가 31개 지역에서 채집되어 가장 넓게 분포하는 종으로 나타났고 가장 많은 개체가 채집된 종은 Distolasterias nipon으로 총 820개체 중 209개체가 채집되었다. 총 29종으로 동해에만 분포하는 종은 15종이었고 동해 연안에서 온대종 16종(55.2%), 한대종 10종(34.5%), 열대종 3종(10.3%)이 분포하는 것으로 나타났다. 현재까지 우리나라 연안에 분포하는 것으로 밝혀진 해성류는 48종이 된다.

  • Some asteroid specimens were collected at a depth of 150 m near Moseulpo in Jeju Island, Korea using fishing nets on October 2014. The specimens were identified as Henricia pacifica Hayashi, 1940 belonging to the family Echinasteridae of order Spinulosida. In the Korean fauna, seven species of genus Henricia were reported of which two species, H. nipponica and H. ohshimai, were distributed in Jeju Island. The morphological characteristics of this species were re-described with illustrations.

  • Asteroid specimens were collected from Shinnam, Gangwondo in the East Sea of Korea with fishing nets on 12 September 2014. The specimens were identified as Henricia reticulata Hayashi, 1940, belonging to family Echinasteridea of order Spinulosida. This species can be distinguished by a larger disc and broader arms compared to those other Henricia species. The morphological characteristics of this species are re-described with illustrations. By previous work of this genus, six species have been reported in the Korean fauna.

  • Some asteroid specimens were collected from the subtidal zone near Gapado, Jejudo Island with fishing net on June 2010. Among them, Anseropoda petaloides (Goto, 1914) which belongs to the family Asterinidae of the order Valvatida turned out to be a new record from Korea. Morphological characters of this species collected at 130 m deep are redescribed with photographs. This species is characterized by its very thin body composed of plates imbricated into each other like scales. Twenty four asteroids are currently known from Jejudo Island, Korea.
