The tonguefish, Cynoglossus robustus and C. abbreviatus (Order Pleuronectiformes, Family Cynoglossidae), inhabits on soft and sand mud bottoms at depth of 20∼85 m around Korea, China and Japan(Nakabo, 1993; Okamura et al., 1970). The tonguefishes are economically important species and are relatively abundant among the fishes found in the Seto Inland Sea(Inaba, 1963: Inaba, 1988). (omitted)

Feeding ecology was compared among the three tonguefishes Cynoglossus abbreviatus, C. joyneri and C. robustus, collected from Seto Inland Sea, Japan, from June 2000 to May 2001. They are benthivores, consuming mainly gammarid amphipods, shrimps, crabs, gastropods, bivalves and ophiuroids. C. abbreviatus consumed greater proportions of ophiuroids whereas C. joyneri and C. robustus ate more amphipods and shrimps. While C. abbreviatus consumed mostly ophiuroids in all size classes, the diets of C. joyneri and C. robustus showed ontogenetic changes in feeding habits; smaller individuals of C. joyneri and C. robustus consumed gammarid amphipods, whereas larger C. joyneri ate shrimps and gastropods, and larger C. robustus fed mainly on gastropods, crabs, bivalves and polychaetes. Cluster analysis based on diet similarities emphasized that the three Cynoglossus species could be categorized on a size-related basis into three feeding groups: smaller C. joyneri and C. rubustus (<25 cm TL) could be classified as group A, and the larger of them (>25 cm TL) as group B, whereas C. abbreviatus was categorized as group C. This means that some degree of resource partitioning can occur among the three Cynoglossus species. The seasonal changes in the diets were also significant for the three Cynoglossus species.

본 연구에서는 한국산 참서대과 어류 3속 8종에 대하여 재검토하고 그들의 검색표를 제시하였으며, 1992년부터 1993년 까지 우리나라 전 연안에서 채집되어진 다음의 6종의 참서대과 어류는 그림과 함께 재기재 하였다; 칠서대 Cynoglossus interruptus, 참서대 C. joyneri, 개서대 C. robustus, 박대 C. semilaevis, 용서대 C. abbreviatus, 흑대기 Paraplagusia japonica. 종전에 보고된 한국산 참서대과 어류 가운데 까지서대 Areliscus trigrammus, 서대기 A. hollandi, 박대 A. rhomaleus는 각각 용서대 Cynoglossus abbreviatus, 물서대 C. gracilis 박대 C. semilaevis의 동종이명이다. 우리나라의 참서대과 어류는 주로 서해와 남해안에 서식하지만 C. interruptus와 C. abbreviatus의 서식지는 남해안에만 한정되어 있으며 C. semilaevis는 서해안과 남해의 서부 연안에, Paraplagusia japonica는 동해를 비롯한 서해와 남해의 모든 연안에 분포하는 것으로 확인되었다.

The re-identification of two Korean tonguefishes, Cynoglossus interruptus and Symphurus orientalis, was carried out using eight specimens collected from Korean waters in 2007 and 2013. C. interruptus is characterized by having a single row of scales between rows connected to the supraorbital line and the middle lateral line, 107–113 dorsal fin rays, 86–89 anal fin rays, and 53–55 vertebrae. S. orientalis is characterized by having a 1-2-2-2-2 ID pattern, 97–100 dorsal fin rays, 83–89 anal fin rays, and 52–55 vertebrae. Molecular analysis using mitochondrial DNA Cytochrome Oxidase subunit I sequences showed that specimens of the two species corresponded well to Japanese C. interruptus and Taiwanese S. orientalis, respectively. Therefore, although several reports have raised questions regarding the distribution of C. interruptus and S. orientalis in Korean waters, morphological and molecular data confirm that these two species are indeed distributed in these waters.
