A single specimen of Festucalex erythraeus, belonging to the family Syngnathidae, was first collected from Seogwipo, Korea, on August 12, 2019. This species is characterized by a low median dorsal snout ridge, and a lateral trunk ridge extending to the last trunk ring. Festucalex erythraeus is similar to the congeneric species, F. rufus: however, it is distinguished by the number of tail rings (32-37 in F. erythraeus vs. 31 in F. rufus). Here, we suggest the new Korean names "Min-sil-go-gi-sog" for the genus Festucalex and "Deung-huin-jeom-sil-go-gi" for the species F. erythraeus.

The previous morphology-based taxonomic frameworks within the family Syngnathidae had emphasized the significance of the male brood pouch and reproductive biology in defining the group. However, several different hypotheses had been proposed by different investigators. This study has been carried out to determine the phylogenetic relationships among 19 species belonging to the order Syngnathiformes with three Gasterosteiformes species as outgroup taxa by using the mitochondrial cytochrome b DNA sequences. Phylogenetic analyses based on neighbor-joining distance, maximum parsimony, minimum evolution and maximum likelihood method strongly supported that the family Syngnathidae, the suborder Syngnathoidei and the order Syngnathiformes were all monophyletic group. Although much of previous morphological analyses were supported by our molecular data, there were some significant discrepancies between molecular and morphological work. Such an interesting result was that the weedy seadragon (Phyllopteryx taeniolatus) strongly grouped together with the New Zealand pot-belly seahorse (Hippocampus abdominalis). Considering the markedly different brooding structure between them, this unexpected result might be explained whether by multiple independent origins of brooding structure or by hybridization between the female Hippocampus and other syngnathid species having individual membranous egg compartment. In addition, the suborder Aulostomoidei was paraphyletic group because the shrimpfish (Aeliscus strigatus), belonging to the family Centriscidae, always grouped together with the family Syngnathidae as a sister taxon.

This study provides a detailed morphological description of larvae obtained from Urocampus nanus and Syngnathus schlegeli male brood fish over 20 days of culture in the laboratory. In both species, mating takes place when several males each spread their brood pouch like a wing to attract a female's attention. When the female begins to swim upward, the males follow her and receive her eggs in their brood pouches. Newborn larvae of U. nanus and S. schlegeli had already completed formation of dorsal and caudal fin rays, but not of pectoral fin rays. Pectoral fin rays were completely formed 15 days after release in S. schlegeli and 20 days after release in U. nanus. The ratio of caudal fin length to standard length increased until 8 days and decreased thereafter in S. schlegeli, while in U. nanus this ratio declined continuously after hatching. The larvae of the two species were very similar in external morphology, but well distinguished by the number of dorsal fin rays (15-16 in U. nanus vs. 39-43 in S. schlegeli), the presence of a membrane under the tail (absent in U. nanus vs. present in S. schlegeli), and the presence of melanophores in the dorsal fin (present in U. nanus vs. absent in S. schlegeli). Based on this study, U. nanus appears to be evolutionally more similar to pipefish than to seahorse.

경남 통영과 거제에서 실고기과 어류 2개체가 채집되었다. 한국에서는 미기록종인 Syngnathoides biaculeatus로 동정되었고, 본종이 포함되는 속(Syngnathoides) 역시 한국 미기록으로 확인되었다. 본 종의 형태는 긴 형태를 띠며, 체륜상 골판으로 덮여 있다. 몸통부는 두부와 꼬리부보다 굵으며, 두부와 몸통은 일자형이다. 주둥이는 긴 관모양이며, 눈 후연에서 아가미 후연까지의 길이보다 길다. 등지느러미는 몸의 뒤쪽에 위치하고, 매우 작은 뒷지느러미가 있으며, 연조이다. Genus Syngnathoides는 "잘피실고기속", S. biaculeatus는 "잘피실고기"로 각각 국명을 신칭한다.

Larval specimens of Halicampus punctatus were collected off Ulsan and Uljin in December 2002 (three specimens) and off Ulsan in December 2003 (one specimen). These specimens are characterized by the following morphological characteristics: rings, 14 + 35 = 49; subdorsal rings, 1 + 3 = 4; dorsal fin rays, 19 - 20; pectoral fin rays, 14 - 15; anal fm rays, 9; head length (HL), 5.8 - 6.7 in the standard length; snout length, 1.9 in HL; snout depth, 3.7 - 5.2 in snout length. The number of caudal fin rays 9 is less than those of the other species in the same genus 10. Wide stripe bands composed of small pigments are shown in the trunk and the tail. Melanophores are not found in the dorsal fin, the pectoral fin, and the anal fin except the caudal fin. The supraoccipital crest is on the head. The frontal ridge is on the dorsal side of front trunk. The blanched ridges on the opercular are fused with a main ridge like a tree branch. A few branched ridges that are small and narrow on the trunk and the tail are fused with the main ridges. We report these specimens as the first record in Korea and name them 'Byeol-sil-go-ki' in Korean.

인도-서태평양산 실고기, Hippichthys penicillus 1개체(표준체장 124.5 mm)가 우리나라 남해도의 동대만으로 유입되는 소하천 하구에서 처음 출현하였다. 본 종은 주둥이가 비교적 길며, 직선형의 몸통 측면 융기선이 꼬리 융기선과 연결되지 않고 항문 앞에서 끊기는 점 등에서 같은 속의 다른 종들과 구별된다. 본종의 신한국명으로 '흰점실고기'를 제안한다.

본 연구는 2015년 5월부터 2016년 12월까지 전라남도 완도군 소안도 일대에서 해마의 서식지 특성 및 산란생태를 밝히기 위해 조사하였다. 해마가 서식하는 조사지점은 주로 거머리말 개체군의 초지가 형성되었다. 거머리말 생육밀도와 생물량(Mean±SE)은 각각 춘계(5월)에 136±14.4shoots/m², 489.8g DW/m²로 가장 높았고, 생육밀도는 추계(10월)에 93±7.0shoots/m², 생물량은 동계(2월)에 122.3g DW/m²로 가장 낮았다. 본 연구 기간 동안 다이빙과 족대 조사를 통해 293개체의 해마가 확인되었고 해마의 전장은 10.1~87.0mm의 범위였다. 수정란 또는 자어를 보육중인 수컷 개체는 2015년, 2016년 모두 5월부터 출현하여 10월까지 채집되었고, 미성어의 출현은 2015년에는 7월, 2016년에는 6월부터 확인되었다. 산란기 특성을 종합적으로 분석한 결과, 해마의 산란시기는 4~10월까지로 추정되었다. 수컷의 보육낭에서 확인된 수정난수 또는 자어수는 38.3±14.8(20~76)개였고 암컷에서 확인된 포란수는 47.2±8.6(31~59)개였다. 해마의 암컷과 수컷의 성비는 1:1.7로서 수컷의 출현비율이 우세하였다.
