초록

표본은 2012년 3월 경상북도 독도주변해역에서 자망에 의해 어획된 것이다. 화살꼴뚜기는 몸통길이 (ML) 22.5-34.2cm (평균 $27.1cm{\pm}2.8$) 이다. 지느러미길이 (FL) 는 몸통길이 (ML) 의 2/3정도인 60%를 차지하였다. 지느러미폭(FW) 은 몸통길이 (ML) 의 약 1/2정도이다. 팔은 몸통길이(ML) 에 비해 짧고 굵으며, 팔길이식은 III>II>IV>I 이었다. 왼쪽 4번째 팔의 말단부 약 30%가 교접기로 되어 있다. 교접기는 아주 작은 흡반 및 거의 흔적적인 흡반이 나열되어있다. 표본 44개체 중 암컷 (♀) 은 23개체, 수컷 (♂) 21개체이었다. 생식소 발달단계는 암컷 (♀) 완숙단계, 수컷 (♂) 방정단계였다.

Forty four specimens (22.5-34.2 cm ML) of Heterololigo bleekeri were collected around Dokdo, East Sea on March 1, 2012. It was identified as H. bleekeri based on the following combination of morphological character: mantle very elongate; fin large, thick, length two-thirds of mantle length; arms very short and small in relation to body size, are formula III>II>IV>I.
