초록

표본은 2010년 7월 12일 부산시 송정주변해역에서 정치망에 어획된 것을 채집하였다. 패각 방사륵은 56개이었다. 제1번 팔은 패각을 붙잡고 있으며, 제1번 팔의 기저부는 팔 전체를 덮을 만큼 매우 큰 편평한 막으로 되어 있었다. 출수기관은 비교적 큰 편이어서 4번 팔의 기저부를 넘어선다. 팔길이식은 4 > $2{\fallingdotseq}3$ > 1이었다. 표본은 암컷이며, 포란수는 155,203 립이었다. 난은 타원형이었다. 조개낙지는 표층 부유성 문어이며, 돌고래의 먹이생물 중 하나이다.

One specimen of Argonauta argo belonging to the family Argonautidae, was collected Songjeong, southeastern coastal water of Korea on July 12, 2010. The specimen, a mature female of 76 mm mantle length and 97 mm shell length. The number of ribs are 56 in shell. The shell is distinct between the arm I's. The I arm has expanded, hemi-discoidal web to which the distal part is fused together. The funnel is large and exceeds the base of arm IV. The arms formula is IV > $II{\fallingdotseq}III$ > I. The specimen was female. Fecundity was 155,203 eggs. This species is pelagic octopus and important prey item of dolphin.
