  • Some sea urchins were collected from the subtidal rocky bottom of Munseom near Seogwipo, Jejudo Island by SCUBA diving from April to May, 2008 and identified on the basis of their morphological characteristics. Among them, Tripneustes gratilla (Linnaeus, 1758) of Family Toxopneustidae was newly recorded from Korea and redescribed on the specimen collected at a depth of 25 m between Munseom and Sekkiseom. The detailed morphological description was presented with the photographs. This species was characterized by the very naked median areas of ambulacral and interambulacral portions and this genus was the first record in Korea. Eighteen echinoids are so far recorded in Jejudo Island, Korea.

  • 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.

  • Colonial ascidian, Eusynstyela monotestis (Tokioka, 1953), is newly reported from Korean waters. The specimens of E. monotestis examined in this study were collected at subtidal zone of Beomseom, Munseom, Seopseom and Chagwido in Jeju-do by SCUBA diving. The genus Eusynstyela Michaelsen, 1904 is also new to Korean waters and it is distinct from other genera by having branchial sac with folds, longitudinal stigmata, hermaphrodite gonads on both sides, 1-2 male follicles in each gonad and body wall with endocarps. Eusynstyela monotestis is distinct from other species by having gonad with only single male follicle. In this paper, detailed descriptions and photographs of Eusynstyela monotestis (Tokioka, 1953) are provided.

  • Xanthid crabs, decapod crustacean, with the black coloured fingers, are easily found under rocks or stones in the intertidal or subtidal zones. Two xanthids, Etisus laevimanus Randall, 1840 and Paraxanthias elegans (Stimpson, 1858), were newly reported in Korean waters as part of continuous taxonomic studies on crabs. The genus Paraxanthias Odhner, 1925 was also reported for the first time in Korea. Of these, the examined specimen of P. elegans showed eight feathery hairs on the subdistal tip of the first gonopod, which differs from the description of Dai and Yang at 1991. Here, the descriptions and illustrations of these species are provided. Korean Xanthoidea currently consists of 30 species belonging to 25 genera.

  • Some gorgonians in the families, Primnoidae and Isididae within the suborder Calcaxonia were collected from subtidal zones between depths of 10 and 45 m in the coastal regions of King Sejong Station ($62^{\circ}13'S$, $058^{\circ}47'W$), Korea Polar Research Institute of Korea Ocean Research and Development Institute (KORDI) by SCUBA diving from 2009 to 2011. Three species in the Primnoidae, $Arntzia$ $gracilis$ (Molander, 1929), $Thouarella$ ($Thouarella$) $antarctica$ (Valenciennes, 1846) and $Onogorgia$ $nodosa$ (Molander, 1929), and also one species in the family Isididae, $Tenuisis$ $microspiculata$ (Molander, 1929) are newly recorded to octocorallian fauna in Marian Cove and Potter Cove of King George Island. These four species have been described in detail.

  • In the present study, we observed a unique association of the flat oyster, Ostrea denselamellosa obtained from a muddy substrate at Haechang Bay, the south coast of Korea in the spring of 2013. Fossilized or semi-fossilized veneriid clam shells, possibly Ruditapes philippinarum, were found adhering to the umbonal area of the flat oyster valves. This unique association of the flat oyster shells with the fossilized clam shells suggested that the flat oyster larvae utilized the clam shells as substrate during settlement. Since availability of clam shells in the muddy subtidal environment is limited, this unique substrata for the flat oyster larvae may limit recruitment of the flat oysters in the bay.

  • A single specimen in the subfamily Coralliophilinae in Family Muricidae was collected from Jeju-do by SCUBA diving survey. It was identified as Hirtomurex nakamurai Kosuge, 1985 based on external morphological characteristics. The Coralliophilinae species, commonly known as coral snails, are broadly distributed in tropical and temperate oceans from shallow subtidal zones up to 1,000 m in depth. To date, only four Coralliophila species in the subfamily Coralliophilinae have been reported from Korean waters. Prior to this report, Hirtomurex species has not been reported from Korean waters yet. As a result of this study, a total of five species in two genera of subfamily Coralliophilinae are recorded as Korean mollusk fauna.
