  <\/p>\n

Le Citron de mer (Doris pseudoargus<\/em>) est un Mollusque du groupe des Gast\u00e9ropodes nudibranches. Il appartient \u00e0 la famille des Doridid\u00e9s.<\/p>\n

L’esp\u00e8ce vit en milieu marin. Elle fr\u00e9quente les environnements rocheux o\u00f9 elle s’installe en particulier sous les blocs.<\/p>\n

Elle est pr\u00e9sente depuis le bas de la zone de balancement des mar\u00e9es, alternativement couverte et d\u00e9couverte par la mer, jusqu’\u00e0 une profondeur de 300 m\u00e8tres environ.<\/p>\n

  <\/p>\n

Le Citron de mer est ais\u00e9ment identifi\u00e9 \u00e0 sa forme et ses dimensions mais aussi \u00e0 ses couleurs et ses ornementations.<\/p>\n

Le corps a une forme ovale et est l\u00e9g\u00e8rement bomb\u00e9 dorsalement. Il peut atteindre une longueur de 120 mm.
\n\u00c0 l’avant il porte deux tentacules en lamelles, et \u00e0 l’arri\u00e8re une couronne d’expansions p\u00e2les et plumeuses correspondant \u00e0 des branchies. Elles sont r\u00e9tract\u00e9es lorsque l’animal est d\u00e9rang\u00e9.<\/p>\n

La surface est verruqueuse, h\u00e9riss\u00e9e de petits tubercules irr\u00e9guliers.
\nElle est g\u00e9n\u00e9ralement marbr\u00e9e, la couleur dominante pouvant \u00eatre le jaune mais aussi l’orange, le rose voire le vert ou le brun.
\nCette coloration assure le camouflage de l’animal dans son environnement. <\/p>\n

  <\/p>\n

Le r\u00e9gime alimentaire du Citron de mer est compos\u00e9 d’\u00c9ponges, notamment de l’\u00c9ponge mie de pain (Halichondria panicea<\/em>) et de l’\u00c9ponge miette de pain (Hymeniacidon perlevis<\/em>).<\/p>\n

La prise alimentaire est r\u00e9alis\u00e9e gr\u00e2ce aux pi\u00e8ces dures associ\u00e9es au bulbe buccal et \u00e0 une radula, langue r\u00e2peuse portant des dents et anim\u00e9e de mouvements de va-et-vient.
\nElles permettent de d\u00e9tacher de petites particules de la proie. Celles-ci peuvent alors \u00eatre aval\u00e9es.<\/p>\n
