초록
1996년부터 1997년까지 서해와 제주도를 비롯한 국내 연안에서 채집된 흉상 어속 어류를 재검토한 결과 Carcharhinus brachyurus, C. dussumieri, C. limbatus, C. plumbeus, C. sorrah의 5종이 분류되었으며, 이 가운데 Carcharhinus dussumieri 흰뺨상어와 C. sorrah 검은꼬리상어는 미기록종으로 확인되었다. 흰뺨상어는 제2등지느러미만 검은색을 띠고, 검은꼬리상어는 꼬리지느러미 하엽과 제2등지느러미, 가슴지느러미 끝에 뚜렷한 검은색을 띠고 있어서 무태상어, 흉상어 등 국내의 기타 흉상어속 어류와 잘 구분되었다. 한편 정(1977)의 C. gangeticus와 C.bracyurus는 각각 C. plumbeus와 C. limbatus임이 명백하였으며, C. limbatus에 대해서는 국명을 남방상어로 하였다.
The taxonomic revision of the genus Carcharhinus in Korea was made based on the shark specimens collected in the western and southern coasts including Cheju Isl. of Korea from July 1996 to April 1997. Five species were recognized from the Korean waters and they are described herein. Among them, two species of Carcharhinus dussumieri (Valenciennes, 1839) and Carcharhinus sorrah (Valenciennes, 1839) were collected for the first time from the Cheju Isl. coast of Korea. Carcharhinus dussumieri differs from other species of genus Carcharhinus in following morphological characters: a black or dark spot on the sencond dorsal fin but no other markings, a small first triangular dorsal fin and a second dorsal fin with a short inner margin, and Carcharhinus sorrah: conspicuous black tips on the ventral caudal lobe, pectoral and second dorsal fins, and low second dorsal with a inner margin.
