エゾフネガイ属

エゾフネガイ属(英:crepidula)、別名スリッパカタツムリ属、スリッパカサガイ属、スリッパシェル属、カリプトレイド属として知られているのは軟体動物門腹足綱に属し、浅海に生息する貝の分類群のことである。本属はカリバガサガイ科（英語版）に属し、同じ科に属する主なものは、カリバガサガイ属（英語版）、 Bostrycapulus、Ergaea、エゾフネガイ属およびMaoricrypta属がある。本属名のエゾフネガイは近年Grandicrepidula属に分類されるようになった。 また、種名を省略してCrepidulaと呼ばれることもある。エゾフネガイ属の種の定義における最近の変更は、DNA配列のデータと解剖学的研究の両方に基づいている。 多くの解剖により、近縁な属との違いが明らかになった。細胞などの組織だけを調べた場合、これらの間の違いは明らかではないが、3つの遺伝子（COI、16S、および28S）のDNA配列によって区別されている。また、右の画像のように、縦に重なって生息している種もいくつかある。 エゾフネガイ属は、その中のさまざまな種が発達、生態学、行動の研究で一般的に利用されている。主な研究は、海洋無脊椎動物における大規模な性転換に関するもので、性転換が環境によるものであることを実証するために使用されてきた。エゾフネガイ属のネコゼフネガイ(Crepidula fornicata)とシマメノウフネガイは、海洋生息地における外来種の研究によく利用された。 エゾフネガイ属の多くの種の単純な殻のために、カリバガサガイ上科の分類は困難である。多くの場合、似たような殻を持つ別々の種は、普遍的または局地的な分布を持つ。この場合、種の同一性か違いを検証するためには、個体の発生またはDNAデータの綿密な調査が不可欠である。 すべての腹足類と同様に、エゾフネガイ属はろ過摂食動物である。成虫は大きな鰓を使って浮遊物から微細藻類をろ過し食べるが、小さな幼体も歯舌を使って基質から藻類をこすり落とすことができるという証拠がいくつかある。 エゾフネガイ属の一部の種は数体が大きい個体が下部に、小さい個体が上部に、縦に重なって生息している。この際、下部にいる個体はメスとなり、上部にいる個体はオスとなる。また、真ん中の方の個体は性が定まっていない。個体の順序や成熟度などが変わった時、性転換がおこる。 エゾフネガイ属は各地で外来種として、その土地の生態系を脅かしているものが多い 。 ネコゼフネガイ(Crepidula fornicata)は、北アメリカの東海岸、フロリダ北部からカナダにまでが原産地である。この種は現在世界中に広まっており、スペインとフランスの北海岸、イギリスの海岸の大部分、そして北海沿岸で非常に侵略的な外来種であると考えられている。サンフランシスコ湾、ピュージェット湾、地中海からも生息が報告されている。Crepidula convexaは、北アメリカの東海岸に自生し、サウスカロライナからニューイングランドまでが原産地である。この種は、ピュージェット湾とサンフランシスコ湾から生息が報告されている。 他に、シマメノウフネガイ(Crepidula onyx)は、カリフォルニアの南海岸とメキシコの北太平洋沿岸が原産地である。この種は現在広く拡散しており、アジアで非常に侵略的な外来種だと考えられている。韓国、日本、香港など東アジアから生息が報告されている。 エゾフネガイ属の種は次のとおりである 。なお、種名を斜体で示す。 Crepidula adunca G.
