田螺

**田螺**泛指**田螺科**（學名：Viviparidae）的淡水腹足綱軟體動物。平均只有拇指頭大小，有角質口蓋（螺厴），殼口相對比較大。螺螄是田螺科動物的通稱。很多淡水魚類喜歡吃田螺。田螺體內很容易生長寄生蟲。

根據在 2005 年的《布歇特和洛克羅伊的腹足類分類》，田螺科屬主扭舌目的成員。

## 分佈

This family occurs nearly worldwide in temperate and tropical regions, with the exception that they are absent from 南美洲.
There are two genera of Viviparidae in Africa: _Bellamya_ and _Neothauma_.

## 分類

舊屬前鰓亞綱的中腹足目，田螺科目前是主扭舌類的成員，約有 17 屬百餘種。根據 2005 年的《布歇特和洛克羅伊的腹足類分類》，田螺科物種大致可分為三個亞科：

* 田螺亞科 Viviparinae Gray, 1847 (1833) - synonyms: Paludinidae Fitzinger, 1833 (inv.); Kosoviinae Atanackovic, 1859 (n.a.)
* 環棱螺亞科 Bellamyinae Rohrbach, 1937 - synonym: Amuropaludinidae Starobogatov, Prozorova, Bogatov & Sayenko, 2004 (n.a.)
* 平圓螺亞科 Lioplacinae Gill, 1863 - synonym: Campelomatinae Thiele, 1929
