  • 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.

  • For the systematic study of Korean Asteroidea the specimens collected from total 69 localities in the South Sea, Korea during the period from April, 1980 to Apirl, 1992 were indentified. As a result, 23 species, 18 genea, 8 families and 5 orders were identified of which two species, Mediaster brachiatus and Stellaster equestris have not been reported in Korea yet. Asterina perctinifera was the commonest species collected from 43 localities of 69 localities. Fifteen species were found in Korea Strait and Cheju Island area, respectively. Fifteen temperate species, 7 tropical species and 3 boreal species were found to be distributed in the South Sea of Korea. The asteroids known so far in Korea tuned out to be 43 species.

  • 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.

  • Twenty-nine species of asteroids are reported to be distributed in the East Sea of Korea. Five species are reported to be distributed in the East Sea of Korea. Five speices are reported for the first time in Korea ; Solaster endeca (Linn, 1771), Lethasterias fusca D'yakonov, 1931, Lethasterias nanimensis chelifera (verrill, 1914), Lysastrosoma anthostictha Fisher, 1992 and Evasterias troscheli alveolata Verrill, 1914. The faunal composition and distribution of the asteroids in the East Sea of Korea are discussed.

  • 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.
