The Japanese codling fish, Physiculus japonica (family Moridae) is recorded as new to the Korean fish fauna. The specimen was fished from the South-Eastern waters off Jeju Island, Korea in March 1999. Standard length of the specimen was 343.2 mm, with a thin barbel on ower jaw, 67 soft second dorsal rays, 71 soft anal rays and 12 lateral-line above scales. Identification key of this specimen as P. japonica in the family Moridae was teethless vomer, chin barbel and well-developed black ventral light organ located on the anterior of anus. We give a new Korean name Dol-dae-gu for P. japonica.

Six adult fish of Laemonema nana, belonging to the family Moridae, were collected in a bottom trawl in the southern coastal waters of Korea. These specimens were characterized by having 46-52 second dorsal fin rays (vs. 57-67 for Lotella phycis and 68 for Physiculus japonicus), two pelvic fin rays (vs. 9 for L. phycis and 6-7 for P. japonicus), and lateral line descending abruptly below the anterior part of the second dorsal fin.

We describe the morphological characteristics of two morids, Gadella jordani and Physiculus japonicus, belonging to the order Gadiformes, based on Korean specimens collected from the Korean ocean. Two specimens of Gadella jordani was first collected from Jeju Island, Korea and the East Sea, Korea, in 2013-2014. This species is characterized by 8, 67-69 dorsal fin rays, 66-71 anal fin rays, 5+13 gill rakers, no barbel on the lower jaw, no vomerine teeth, and a ventral luminous organ closer to the anus than to the interventral line. We described it as the first record to the Korean fish fauna, and proposed the new Korean name "Min-su-yeom-dae-gu-sok" for the genus Gadella, and "Min-su-yeom-dae-gu" for the species G. jordani. Physiculus japonicus was first reported by Koh and Moon in the year 1999 based on a single specimen in Korea. However, no study has been attempted to describe the morphological characteristics in Korea since then. In 2013-2014, three specimens of P. japonicus was collected from Jeju Island, Korea and the East Sea, Korea, and we redescribe P. japonicus in detail. This species is characterized by 9-10, 63-64 dorsal fin rays, 70-73 anal fin rays, 3+7-8 gill rakers, a short barbel on the lower jaw, and a ventral luminous organ equidistant between the interventral line and the anus.

A total of 28 Laemonema nana larvae, 1.4~10.5 BL (body length), were collected by bongo net and trawl-shaped fish larvae net in the coastal area of Cheju Island during 1998~1999. This species was found in around sea of Cheju Island, Korea Strait and southwestern East Sea. This paper describes morphological features of these specimens throughout their development. 1) The soft ray of fin appeared at about 4.5 mm BL and attained to a fixed number at about 6.8 mm BL. 2) There were two large pigments in the head of larvae less than 4 mm BL. 3) A large pigment in the middle of tail appeared at about 2 mm BL was spread to the caudal peduncle at about 9 mm BL. 4) Two large pigment in the base of anal fin appeared at about 2 mm BL were spread out 2/3 of anal fin to caudal fin at about 9 mm BL. 5) A new Korean name "Chal-Bun-Su-Yum-Dae-Gu" is proposed for this species.
