左錐螺科

左錐螺科（學名：Triphoridae），又名錐折螺科page1=39、三孔螺科shelldoc_200001或三口螺科Pan 1998，是新進腹足類支序腹足綱軟體動物之下翼舌類非正式群組一個海螺的科。本科物種的體積皆非常小，幾乎全部都可歸類為微小貝，而且幾乎所有貝殼的手性皆為左旋WoRMS_131。在較舊的分類，本科是異腹足目的成員TaiBNET。

**型態描述**
本科物種螺殼的體積皆屬小型，而且有很多層捲曲，
and extremely high-spired, with numerous narrow whorls which often have distinctive sculpture. 
本科物種大多數螺殼的手性皆為左旋WoRMS_131，這一點在海洋腹足綱軟體動物來講比較罕見Marshall 1983。
