  • Ultrastructure of fertilized egg envelope in the tomato clown anemonefish (Amphiprion freatus) was examined by mean of light, scanning and transmission electron microscopies. The fertilized egg of tomato clown anemonefish was of non-transparent, ellipsoidal, adhesive and non-floted type, and there were numerous oil droplets in the yolk sac and adhesive filaments in the area of the animal pole. The outer surface of egg envelope was smooth. The fertilized egg envelope consisted of two distinct layers; a non-adhesive outer electron-dense layer and an inner layer, consisting of five horizontal low electron-dense lamellae alternating with the middle electron dense interlamellae.

  • A new marine sponge, Antho (Acarnia) seogwipoensis n. sp., of the family Microcionidae, was collected from Seogwipo-si, Jeju-do, Korea, about 100 m in depth using a gill net on 1969. The genus Antho Gray, 1867 including Demospongiae, Poecilosclerida, Microcionidae, is a large group of sponges. About 100 species in Antho were reported from worldwide. The genus Antho contains five subgenera: Antho, Acarnia, Isopenectya, Jia, and Plocamia. Among them, about 30 species in Acarnia were described in world sponge. A new sponge's body shape is branching, size up to 124 mm wide, 213 mm high, 3-8 mm thick in branch and 7-9 mm thick in stalk. Antho (Acarnia) seogwipoensis n. sp. is similar to A. (A.) novizelanicum Ridley and Duncan, 1881 based on their spicules type and skeletal structure, but differs in the spicules dimension and growth form. This new species is branched growth form and have three kinds of toxa.

  • Fifteen species of poecilostome copepods associated with marine invertebrates, including ten new species, are recorded from intertidal zone in Thailand. New species are Hemicyclops cornutus n. sp. and Hemicyclops parapiculus n. sp. in the family Clausidiidae, Presynaptiphilus trifurcatus n. sp. in the Synaptiphilidae, Anchimolgus kantariensis n. sp. and Anchimolgus palmatus n. sp. in the Anchimolgidae, Kelleria vasfera n. sp. in the Kelleridae, Pseudanthessius stenosus n. sp. and Pseudanthessius phuketensis n. sp. in the Pseudanthessiidae, Doricidola pattayensis n. sp., and Lambanetes mollis n. sp. in the Rhynchomolgidae. Five species are new records of Thailand: Critomolgus gemmatus (Humes, 1964), Doridicola cuspis (Humes, 1964), Doridicola inaequalis (Humes and Ho, 1966), Indomolgus brevisetosus (Humes and Ho, 1966), and Lambanetes stichodactylae Humes, 1982. The female of Lambanetes stichodectylae is described for the first time in the world.

  • The result of the screening of lectins on 28 species of marine shell fishes(mollusks) showed that 10 species (Tapes philippinarum, Cyclosunetta menstrualis, Neptunea arthritica cumingii, Omphalius pfeifferi carpenteri, Chlorostoma argyrostoma turbinatum, Chiorostoma argyrostoma lischkei, Semisulcosira corea, Neptunea polycosta, Babylonica japonica, Noverita didyma) were present hemagglutinating properties to human A, B, and O group, and animal blood erythrocytes. A new lectin from Tapes philippinarum. was isolated and partially characterized. The lectin was purified by (NH$_4$)$_2$SO$_4$ precipitation and ion exchange chromatography on DE 53 column. Six fractions were obtained from DE 53 column by salt gradient elution but only 0.3M, and 0.4M NaCl fraction had strong lectin activity. On its 0.3M NaCl fraction, purity was identified by polyacrylamide gel electrophoresis. This lectin was inhibited by N-acetyl-D-galactosamine. It seems that two kinds of lectin react as antigen by immunochemical studies.

  • A halacarid species of the genus Copidognathus is newly reported from Korea: C. daguilarensis Bartsch, 1997, which was described from Hong Kong. It is redescribed herein with detailed illustrations. Korean specimens coincide well with the original description, however, they showed two minor morphological discrepancies from it: quite shorter second palpal segment than the fourth and a modified dorsal seta on the second palpal segment. Korean specimens were rather smaller than the type specimens from Hong Kong, however, they did not show significant differences in the length to width ratios of important body parts. The number of perigenital setae was more variable in the Korean males, ranged 24-29 setae, versus 25-26 in Hong Kong's. Copidognathus daguilarensis is reported for the first time outside the type locality, and joins as the second member of the gibbus group in the northwest Pacific.

  • An arenicolous halacarid, Scaptognathus magnus Abé is first recorded from Korea, which was collected from littoral coarse sandy bottom around Simnibawi Rock off Gangreung in the east coast of South Korea. The remarkable characteristics of this species are large body with idiosoma more than 470 ㎛ long, nearly trapezoidal anterior dorsal plate, and a unique chaetotaxy of bipectinate setae 5-3-3-3 on tibiae I-IV. The characteristics of Korean specimens coincide well with the original description from Hokkaido, Japan, except for the number of parambulacral setae on tarsus III and the weak median claws. Detailed illustrations and scanning electron microscope photographs based on Korean specimens are provided.

  • A harpacticoid copepod, Microarthridion littorale (Poppe, 1881), is newly recorded in Korea. Microarthridion species can be distinguished from each other by a combination of the number of the antennular segment, the number of the seta on the antennary exopod, and the armature of the thoracopod legs. Korean materials examined coincide well with M. littorale on these well-known characteristics. However, there are some minor differences in the ornamentations of the maxilliped and swimming legs. The specimens show additional sexual dimorphisms in the setae on enp-3 of P1 and exp-3 of P2-P4. Morphological diversity of so-called M. littorale is also discussed here with detailed features.

  • The Cymatium Roding, 1798 is a small- to large-sized marine gastropod genus. Three species has been reported thus far for Cymatium in the Korean waters. In general, Cymatium encausticum (Reeve, 1844) is known to occur in tropical seawaters including the Philippine Islands along with its congeners C. gutturnium, C. springsteeni, and C. exile. A single individual of the species was collected from Jejudo Island by SCUBA diving and morphological features were observed using a stereomicroscope. This is the first study to report the occurrence of Cymatium encausticum (Reeve, 1844) from the Korean waters, providing a detailed description of the species with the illustration for the shell morphology.

  • A single specimen (149.9 mm TL) of sagami grenadier, Ventrifossa garmani was collected from Korea waters. This species is similar to Coelorinchus spp. in body shape, but is distinguished by a short and rounded snout. It is characterized by having the serrated second dorsal spine in the first dorsal fin, a triangular spine on the scale, seven branchiostegal rays and six scales below middle of first dorsal fin. We describe this species as the first record to Korean fish fauna and propose the Korean name "Kkeo-kkeul-meo-ri-min-tae-sok" for this genus, and "Kkeo-kkeul-meo-ri-min-tae" for this species.
