Omobranchus loxozonus is first recorded from Korea based on 31 specimens (32.3~71.5 mm SL) collected from the southern coastal waters of Jeju Island. The species is characterized by having XII~XIV, 19~22 dorsal fin rays, II, 22~24 anal fin rays, and a conspicuous color pattern on the body. A new Korean name "Gu-reum-be-do-ra-chi" is proposed for the species.

Xiphasia setifer is reported for the first time from the South Sea of Korea based on a single specimen (291.0 mm SL) collected in September 2010. This species is characterized by the origin of the dorsal fin located vertically above the anterior margin of the eye; dorsal fin rays XIV, 114; anal fin soft rays 114, and vertebrae 130. The new Korean name of the genus Xiphasia is proposed as "Galchi-be-do-ra-chi-sok" and the Korean name of X. setifer as "Gal-chi-be-do-ra-chi", following Yamada et al. (2009).

Based on six specimens collected from eastern coast of Jeju Island, Korea, Istiblennius dussumieri is described as a new Korean record representing the northernmost occurrence of the species in the Indo-Pacific Ocean. The species is characterized by having a dark spot between first and third dorsal spines, branched orbital cirrus, and lacking nape cirri. A new Korean name, "Geom-eun-jeom-be-do-ra-chi" is proposed for the species.

Based on a single adult and two juvenile fishes collected from the coastal waters of Jeju Island, Scartella emarginata was redescribed as the first reliable record from Korea. The species is characterized by having a median fringe of cirri on head, short branched supraorbital cirrus, and by lacking canine teeth on both jaws.

The blenniid fish, Istiblennius dussumieri (Valenciennes) was reported on the basis of six specimens collected from rocky shores on the Yokonami Peninsula, Kochi Prefecture, southern Japan. This species was characterized by wavy, dusky stripes on its dorsal fin, 14 pectoral fin rays, 38 to 42 vertebrae, branched supraorbital cirrus, finger-like nasal cirrus, seven to ten vertical, dark bands on the body and canines absent on both jaws. Although the occurrence of this species may be due to larval transport by the Kuroshio Current, this is the first record of I. dussumieri from Japan represents a remarkable northern range extension of the species in the western Pacific Ocean.

Two specimens of Omobranchus fasciolatoceps (33.8~46.7 mm SL) were collected from oyster reefs of Osu-ri, Geoje-myeon, Geoje-si, Gyeongsangnam-do, Korea. This species is characterized by having 32~34 dorsal fin rays, 24~25 anal fin rays, 13 pectoral fin rays, 2 interorbital pores, 8 circumorbital pores, 5~7 lateral line tubes, fleshy crest on head and sexual dimorphism in female that have lost the posterior canines in both jaw. We propose the new Korean name, "Ppul-be-do-ra-chi", for the species.

The investigation of the fishes was conducted based on the specimens from the Wooi-Islands, southern west coast of Korea in August, 1998. The fishes were composed of 25 species and 22 genera belonging 15 families. Among them, the gobiid fishes composed of 6 species and the combtooth blennies of 3 species. The gobiid fishes, Chasmichthys dolichognathus, Tridentiger trigonocephalus and Synechogobius hasta were most commonly found in the intertidal area of these islands. One specimen collected from tidepool at tentatively identified as Abudefduf bengalensis of the family Pomacentridae for the first time from Korea. This species was characterized by having seven black bars on the trunk of body. A new Korean name "Huk-jul-dom" is proposed for this species.

This research has carried out to make a data base of taxonomic research. That Data base explains about spawning behavior, egg development, and morphologic development of variable sabretooth blenny. Fertilized egg was demersal egg which is white and opaque. The number of oil glouble were 10~11, and the size of egg was 0.90~1.43 mm (average rate $1.11{\pm}0.23mm$, n=10). Breeding water temperature was $25.5{\sim}28.5^{\circ}C$ (average rate $27.0^{\circ}C$), and salinity was 32.5~33.5‰ (average rate 33.0‰). After 24 hours from 2 cells, the process of egg development was reached to Blastula stage. Moreover, after 330 hours from 2 cells, nostrils and eyes were formed. Egg membrane was pierced by the head, and the hatch began. After the hatch, postlarvae had 2.59~3.02 mm (average rate $2.81{\pm}0.25mm$, n=5) of whole length, and the mouth and anus were opened. Yolk sac and oil glouble were absorbed. After three days from hatch, prelarvae were 3.02~3.07mm(average rate $3.04{\pm}0.04mm$) of whole length, and caudal fin was grown with round shape. After 13 days from hatch, prelarvae had 3.04~3.20 mm (average rate $3.12{\pm}0.11mm$) of whole length, and they could eat food with upper jaw and bottom jaw.

This study was conducted to observe the spawning behavior and early life histroy of elegant blenny, Omobranchus elegans reared in the laboratory. The elegant blenny were caught at Dolsan lsland, Yeosu-si, Jeollanamdo from June in 2012. As a result of observeation, male fish attracted female continuously and guide lead to spawning site and clean the surface of inner pant in oyster shell or barnacle shell. Female left after spawning and male protected their eggs until they had hatched out. The fertilized eggs were spherical in shape (mean diameter: 1.06 mm; mean oil globule diameter: 0.24 mm) and transparent. Larvae hatched at 203 hrs 40 mins after fertilization at $25.5{\sim}28.5^{\circ}C$ (mean $27.0^{\circ}C$). The newly hatched larvae were 3.04~3.09mm(mean 3.06 mm, n=10) in total length and their mouth and anus were already opened. They began to eat rotifer and transformed to postarvae stage. 10 days after hatching postlarvae was measured 6.39~6.45mm(mean 6.42 mm, n=10) in total length. 60 days after hatching juvenile was measured 21.5~22.2 mm (mean 21.8 mm, n=10) in total length with dosal fin rays XI-22; ventral fin rays I-2; anal fin rays II-23; caudal fin rays 21; pectoral fin rays 13.
