  • Mormonilla phasma is redescribed, based on the specimens from the Northeastern Pacific. M. phasma in the study area has the following morphological characteristics; second endopodal segment of mandible partly fused to basis and a distinct three-segmented exopod of mandible in anterior view and one indistinct segment in posterior view which are different from the description given by Boxshall (1979). In addition the first and the second endopodal segments of leg 1 were also separated indistinctly. Other morphological characteristics are similar to those reported in previous studies. The morphological anomalies in endopodal segments of the leg 1, unknown up to now are also discussed. This study is the first report on the distribution of M. phasma in the Northeastern Pacific.

  • Hypoptychus dybowskii, the Korean sandlance, is widespread in cold areas of the North Pacific. Although H. dybowskii has been considered to occur on the coast of Hamgyeongnam-do in Korea, the species is also distributed along the coast of Goseong-gun, Gangwon-do, south of Hamgyeongnam-do in the eastern part of the Korean Peninsula on the basis of newly collected specimens. In addition, many Koreans confuse H. dybowskii and Ammodytes japonicus (= A. personatus for Korean specimens) because the Korean common name or dialect of both species is "Yang-mi-ri", yet the two species differ in their external morphology. Hypoptychus dybowskii differs from A. japonicus in the location of the origin of the dorsal fin and the number of dorsal and anal fin rays.

  • The snapping shrimp Alpheus bisincisus is redescribed on the basis of nine specimens collected in southern Korea. This species is readily distinguished from the other reported species of the Edwardsii group of Alpheus from Korea (A. heeia, A. hoplocheles, A. japonicus, A. lobidens, A. malabaricus, A. pacificus, A. richardsoni, and A. sudara) by having the rostrum and rostral triangle on the carapace flattened dorsally and sharply demarked, and by the presence of overhanging orbitorostral grooves.

  • Using the criteria of previous study, we analyzed the morphological characters of 66 specimens of the Sebastes pachycephalus complex collected from Korea between 2008 and 2013. As a result, the 37 specimens were identified as Sebastes nudus, and the remaining specimens as Sebastes pachycephalus. Sebastes nudus is characterized by the absence of scales below the base of the dorsal fin spines; the absence of dark spots on the dorsal, anal, and caudal fins; and the presence of distinct yellow or brownish-red markings on the dorsum (when fresh). The most similar species S. pachycephalus differs from S. nudus in having minute scales below the base of the dorsal fin spines. We propose the new Korean name "Hwang-jeom-gae-bol-rak" for S. nudus, and redescribe S. pachycephalus.

  • The first zoea of Microcassiope orientalis is described and illustrated from laboratory hatched materials. Comparisons with previous studies of the first zoeal stages in the Xanthidae from Korean waters, revealed that some former studies were incorrected. The first zoea of M. orientalis described by Ko was identical to the first zoea of Macromedaeus distinguendus described by Terada. In addition, zoeal stages of Nanocassiope granullipes described by Ko & Clark was revealed the zoeal stages of M. cassiopes. So, the first zoea of M. orientalis is redescribed and illustrated in detailed with color photo herein, and compare its morphological characteristics with previous described zoea of N. granulipes by Ko & Clark.

  • 2008~2010년 사이에 우리나라 부산 및 광양에서 채집된 당멸치, Elops hawaiensis 4개체의 형태특정을 상세히 재기재하였다. 본 종은 아래턱의 봉합부와 협부 사이에 후판을 가지며, 입을 닫았을 때 전상악골의 치대 전체가 노출된다. 한국산 당멸치는 척추골수이 65~67개, 뒷지느러미 연조수가 14개, 측선비늘이 95~101개를 가지는 것이 특징적이었으며 이전 연구결과와 약간 달랐다. 미토콘드리아 DNA cytochrome b 480 bp의 염기서열을 분석한 결과, 우리의 4개체는 E. hawaiensis와 99.8~100% 일치하였다. 따라서, 우리 결과는 당멸치가 척추골 및 뒷지느러미 계수에서 지역적 변이가 존재할 것이라는 사실을 제시한다.
