螔螺屬

螔螺屬（學名：Limacina）是翼足目螔螺科之下的一個海洋腹足綱軟體動物門屬，即俗稱「海蝴蝶」的一種。本屬物種是腹足綱之下其中一個物種非常豐富的屬。 本屬的學名「Limacina」本身的意思其實就是「像蝸牛」 作為一種在海洋的浮游生物界生活的腹足綱物種，螔螺屬透過拍動牠們的一雙擬足（亦作疣足，parapoida）來在水中暢泳，所以得來「海蝴蝶」的美名。 海蝴蝶是有殼翼足類支序（Thecosomata）的成員，與之相對的是屬於裸殼翼足類支序（Gymnosomata）的海天使。這兩個支序的成員合組成為翼足類。兩者的分別在於有殼翼足類的成員的背上還留有一個或大或小的殼，但裸殼翼足類的殼已完全褪化。 本屬物種同時有化石種及生存種，分別如下： † Limacina atypica (Laws, 1944) (recent) Limacina bulimoides (d'Orbigny, 1836)- Bulimoid pteropod.
