- Hwan–Sung Ji, J. Choi, K. Choi, S. Yoon, Dong Woo Lee, Jin-Koo Kim
- 31 December 2014
An analysis of the partial 12S rRNA sequences (849 base pairs) of mitochondrial DNA showed that the authors' specimens must be Ophisurus macrorhynchos because their sequences were concordant with those of the adult O. macrorHynchOS (genetic distance).
A new species of prickleback, Dictyosoma tongyeongensis (Perciformes: Stichaeidae) from the South Sea of Korea
- Hwan–Sung Ji, Jin-Koo Kim
- 30 November 2012
The neighbor-joining tree using mtDNA COI and nDNA RAG2 shows the reciprocal monophyly of the new prickleback.
First Description of the Adult Scolecenchelys aoki (Ophichthidae, Anguilliformes) Collected from the South Sea of Korea, with Comments on the Synonym Scolecenchelys borealis
- Hwan–Sung Ji, M. Kim, Jin-Koo Kim
- 31 October 2013
The adult S. aoki is characterized by several morphological features: vertebral formula 59-55-135; preanal lateral pores 55; infraorbital pores two; teeth on upper jaw visible externally when the mouth is closed; the dorsal fin originates just behind the anus.

It is surmised that the hatched preleptocephali of M. cinereus were transported from offshore areas in the East China Sea to Jeju Island and the Korea Strait by the Kuroshio and Tsushima Warm Current.
Molecular phylogeny of the families Pleuronectidae and Poecilopsettidae (PISCES, Pleuronectiformes) from Korea, with a Proposal for a new classification
- Hwan–Sung Ji, Jin-Koo Kim, Byung-Jik Kim
- BiologyOcean Science Journal
- 19 July 2016
A molecular phylogeny supported the reciprocal monophyly of the three genera, Cleisthenes, PleuronECTes and Pseudopleuronectes, and found that the genus Poecilopsetta is clearly distinct from Pleuronectidae at the family level.
Four newly reported ophichthid leptocephali species revealed by mitochondrial 12S rDNA, with implications of their occurrence in Korea
- Hwan–Sung Ji, Hae-Won Lee, B. Hong, Jin Koo Kim
- 1 October 2012
Four species of ophichthid leptocephali were identified using 12S rDNA sequences, and the new Korean name ‘Dong-hae-mul-baem’ for S. borealis and E. uropterus is proposed.

- Hwan–Sung Ji, Jeong-Ho Park, Tae-Woo Ban, Jin Koo Kim
- 31 October 2012
This species of snailfish, Careproctus notosaikaiensis, is described as the first record to Korea, and the new Korean name, “Dong-hae-bun-hong-ggom-chi” is proposed.
