旋螺屬

旋螺屬（學名：Gyraulus），又名圓口扁蜷屬，為腹足綱泛有肺類扁卷螺科，體型細小，大多數為會呼吸空氣的淡水螺。部分物種乃中國特有物種。

本屬物種最早出現的時間，根據化石紀錄，可以上推至早白堊世，一直延續至今。在今日華北地區的熱河群義縣組的湖底沉積物（具體位置在今日的北京城郊鄰近河北省的下莊鄉）發現本屬物種的化石，年代可上遡至1.25億年前。

微細的物種Gyraulus crista在技術上雖然仍是一隻有肺類的腹足綱物種，這些動物其實並不會在空氣中呼吸，而是依靠充滿了水的外套膜。

## 分佈

本屬物種廣泛分佈於全北區。

## 習性

旋螺屬在淡水的水生植物上生活。

## 型態描述

螺殼半透明，質薄，體型小，而且大多數都是平旋殼。

## 物種

WoRMS記載本屬已紀錄的名稱達420個，當中已接受的現生種及化石種名稱也有241個。過往旋螺屬的物種可以再分為以下三個亞屬：

- subgenus Torquis Dall, 1905
- subgenus Lamorbis Starobogatov, 1967
- subgenus Armiger Hartmann, 1843

但這種分類現時只被作「另類表達方式」來處理。
