【裂螺科】
裂螺总科（学名：Fissurelloidea Fleming, 1822，亦作裂裙螺总科或透孔螺总科），其下只有裂螺科（学名：Fissurellidae Fleming, 1822，亦作裂裙螺科、钥孔䗩科page3=18或透孔螺科shell_3375），是古腹足类支序之下的一个海洋腹足纲软体动物的科。本总科的物种因其锥状螺壳的螺尖上有一个小孔，是海螺的一个特化体。由于整个螺壳的外形就像一条裂开了一条缝的裙摆那样，所以被称为裂裙螺。
根据2005年《布歇特和洛克罗伊的腹足类分类》基本上包括了各种笠螺，覆盖了原来原始腹足目的大多数物种。
==分布==
本科物种的分布是世界性的，从冰冷的寒带到热带都有其物种存在。
==习性==
本科物种一般居住在潮间带下部深水区的岩面或岩底。
