左錐螺科

**左錐螺科**（），又名**錐折螺科**、**三孔螺科**或**三口螺科**，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。在較舊的分類，本科是異腹足目的成員。

## 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，這一點在海洋腹足綱軟體動物來講比較罕見。

## 分類學
布歇和羅克魯瓦的腹足類分類 (2005年)列出左錐螺科物種可分為下列三個亞科：
*三口螺亞科 Iniforinae 
*Metaxiinae Marshall, 1977
*左錐螺亞科 Triphorinae
