多旋螺屬

多旋螺屬（學名：Anisus）是腹足綱之下的一個可呼吸空氣的淡水螺的屬。原屬有肺目基眼亞目，今屬異鰓類泛有肺類喜溼螺類支序的扁卷螺科扁卷螺亞科扁卷螺族。 本屬所有物種的螺殼都是左旋的平旋壳（planispiral），與一般腹足綱物種的外殼形狀不同。外殼看似是右旋，但其實是螺把殼上下顛倒來揹在身上，使左旋的外殼看起來像是右旋。 Anisus (Spiralina) Martens, 1899 (junior homonym of Spiralina Chaster, 1898; junior synonym) Paraspira Dall, 1905 Paraspira (Paraspira) Dall, 1905 Planorbis (Anisus) Studer, 1820 (combination not accepted) Spiralina Martens, 1899 (junior homonym of Spiralina Chaster, 1898; junior synonym) 本屬包括下列各個物種： 拟旋多旋螺 Anisus paravortex（Ping & Yen） 扭曲多旋螺 Anisus contortus（Linnaeus） 本屬包括以下各個亞屬： Subgenus Anisus Anisus calculiformis (Sandberger, 1874) † Anisus komarovae Prysjazhnjuk, 1974 † Anisus krambergeri (Halaváts, 1903) † Anisus laskarevi Milošević, 1976 Anisus leucostoma (Millet, 1813) † Anisus septemgyratiformis (Gottschick, 1911) Anisus septemgyratus (Rossmässler, 1835) Anisus spirorbis (Linnaeus, 1758) - the type species of the genus Anisus strauchianus (Clessin, 1884) Subgenus Anisus (Costorbis) Lindholm, 1926 † Anisus densecostatus Schütt, 1994 Subgenus Disculifer C.
