서식지가 서로 다른 이매패류 3종 (꼬막, 지중해담치 및 개조개)의 당면체낭의 위치와 당면체를 형태학적인 측면에서 기재하였다. 당면체낭은 후위와 연결되어 있었으며, 당면체는 당면체낭에 위치하고 있었다. 3종의 당면체는 반투명의 젤라틴 형태의 긴 원뿔형으로 탄성을 가지고 있었다. 꼬막과 지중해담치의 당면체 내부에는 적황색의 나선형 필라멘트가 존재하며, 개조개의 당면체에는 기저부에서부터 말단부까지 희고 긴 관이 존재하였다. 각장에 대한 당면체의 상대길이비는 꼬막은 47.69, 개조개는 64.20%였으며, 지중해담치의 각고에 대한 상대길이비는 48.97%였다. 육중량에 대한 당면체의 상대무게비는 꼬막과 지중해담치는 0.54%였으며, 개조개는 0.39%였다.
The location of the style sac and morphology of the crystalline style were described morphologically in three bivalve species (Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus) which inhabited in different area. The style sac of them was connected to the posterior stomach. There was the crystalline style in the style sac. The crystalline style of three species was long circular cone of translucent gelatin form, which was hard and elastic. There was a red-yellow and spiral filament inside the crystalline style of Tegillarca granosa and Mytilus galloprovincialis. A white and long tube was located from basal portion to the end of crystalline style in Saxidomus purpuratus. RLC (relative length of crystalline style) of Tegillarca granosa, Mytilus galloprovincialis and Saxidomus purpuratus was 47.69, 48.97, 64.20% and RWC (relative weight of crystalline style) was 0.54, 0.54, 0.39%, respectively.
