Crepidula
Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.

履螺屬（學名：Crepidula）是海螺的一屬，屬於舟螺科的海洋腹足纲软体动物。 履螺屬可能是舟螺科下最為人所知的一屬。其下多個物種在發育、生態及行為方面都有不少研究。 它們一直是海洋無脊椎動物突發性別轉變（英语：protandrous sex-change）研究的主要焦點，並已用於證明性別轉變可經由環境介導的（性別變化的時間取決於與其他螺體的關聯）。 大西洋舟螺及拖鞋舟螺最常用於海洋棲息地的入侵物種的研究

Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
These recent changes in the definition of Crepidula are based on both DNA sequence data as well as anatomical work. Dissections of various calyptraeids show that species that are now placed in Grandicrepidula and Maoricrypta are anatomically very different from the true Crepidula. If only the shells are examined this difference is not apparent. This distinction is supported by DNA sequence data from 3 genes (COI, 16S and 28S).
