L’Anomie pelure d’oignon (Anomia ephippium<\/em>) est un animal marin appartenant au groupe des Mollusques bivalves, et repr\u00e9sentant la famille des Anomiid\u00e9s.<\/p>\n

Cette esp\u00e8ce est pr\u00e9sente depuis la partie basse de la zone intertidale, alternativement immerg\u00e9e et \u00e9merg\u00e9e par la mar\u00e9e, jusqu’\u00e0 environ 200 m\u00e8tres de profondeur. Elle fr\u00e9quente les milieux rocheux, vivant fix\u00e9e sur des supports solides comme les rochers ou les coquilles. <\/p>\n

  <\/p>\n

L’Anomie pelure d’oignon est identifi\u00e9es aux caract\u00e9ristiques de sa coquille, dont le diam\u00e8tre peut atteindre 60 mm, et form\u00e9e de deux valves diff\u00e9rentes l’une de l’autre.<\/p>\n

La valve apparente de l’animal correspond \u00e0 la valve gauche. De couleur blanch\u00e2tre avec des nuances de rose, de beige ou de bleu, elle est l\u00e9g\u00e8rement bomb\u00e9e et pr\u00e9sente des stries de croissance sinueuses. Son pourtour \u00e9pouse les reliefs du substrat sur lequel l’animal est fix\u00e9 alors que sa surface peut \u00eatre \u00e9cailleuse, creus\u00e9e de sillons ou lisse.
\nLa valve droite est invisible, accol\u00e9e au substrat.<\/p>\n

  <\/p>\n

L’Anomie pelure d’oignon se nourrit de particules en suspension dans l’eau de mer.
\nUn courant d’eau traverse sa cavit\u00e9 pall\u00e9ale et ses branchies, g\u00e9n\u00e9r\u00e9 par les cils que portent ces derni\u00e8res.
\nL’appareil branchial assure simultan\u00e9ment la capture des particules alimentaires apport\u00e9es par l’eau et les \u00e9changes gazeux respiratoires. Les particules pi\u00e9g\u00e9es sont achemin\u00e9es vers la bouche.
\nEn raison ce mode de prise de nourriture, l’esp\u00e8ce est qualifi\u00e9e de suspensivore, ou de microphage filtreuse.<\/p>\n
