Abstract

A smooth hammerhead, Sphyrna zygaena, was caught from the coastal water of Boryeoung-si, Chungcheongnam-do, Korea in June 13, 2014. The shark had a total of 23 fetuses in its body. There were 12 males and 11 females. The total length of the young sharks ranges from 49.0 cm to 54.7 cm. This collection suggested that western coastal water of Korea is a birth ground of smooth hammerhead, Sphyrna zygaena.

2014년 6월 13일에 충청남도 보령시 연안의 안강망에 의해 귀상어 1개체가 포획되었으며, 이 귀상어는 모두 23마리의 새끼를 임신하고 있었다. 성비는 수컷 12마리, 암컷 11마리였고, 새끼 상어의 전장범위는 49.0~54.7 cm였다. 이러한 전장범위는 귀상어의 태어날 때 크기이며, 우리나라 서해 연근해가 귀상어의 출산장인 것으로 판단된다.
