【旋螺属】
旋螺属（学名：Gyraulus），又名圆口扁蜷属shell_1898，为腹足纲泛有肺类扁卷螺科，体型细小，大多数为会呼吸空气的淡水螺page1=126。部分物种乃中国特有物种。
本属物种最早出现的时间，根据化石纪录，可以上推至早白垩世，一直延续至今。在今日华北地区的热河群义县组的湖底沉积物（具体位置在今日的北京城郊邻近河北省的下庄乡）发现本属物种的化石，年代可上溯至1.25亿年前。
微细的物种Gyraulus crista在技术上虽然仍是一只有肺类的腹足纲物种，这些动物其实并不会在空气中呼吸，而是依靠充满了水的外套膜。
==分布==
本属物种广泛分布于全北区。
==习性==
旋螺属在淡水的水生植物上生活。
==型态描述==
螺壳半透明，质薄，体型小，而且大多数都是平旋壳shell_1898。
==物种==
，WoRMS记载本属已纪录的名称达420个，当中已接受的现生种及化石种名称也有241个WoRMS_153936。过往旋螺属的物种可以再分为以下三个亚属：
* subgenus Torquis Dall, 1905
* subgenus Lamorbis Starobogatov, 1967
* subgenus Armiger Hartmann, 1843
但这种分类现时只被作「另类表达方式」来处理。
