  <\/p>\n

Le Buccin ond\u00e9 (Buccinum undatum<\/em>) est un Mollusque Gast\u00e9ropode appartenant \u00e0 la famille des Buccinid\u00e9s.<\/p>\n

S’il est parfois rencontr\u00e9 dans la zone intertidale, alternativement couverte et d\u00e9couverte par la mar\u00e9e, il fr\u00e9quente g\u00e9n\u00e9ralement la frange de c\u00f4te toujours immerg\u00e9e, jusqu’\u00e0 une profondeur de 200 m\u00e8tres environ.<\/p>\n

Il \u00e9volue aussi bien en milieu rocheux qu’en milieu sableux.<\/p>\n

  <\/p>\n

Le Buccin ond\u00e9 est un Gast\u00e9ropode de grande taille, dont la coquille peut atteindre 120 mm de haut.<\/p>\n

\u00c9paisse, elle poss\u00e8de un apex pointu, comporte le plus souvent six tours de spire, et pr\u00e9sente une ouverture ovale prolong\u00e9e par une courte expansion creus\u00e9e d’une goutti\u00e8re, le canal siphonal.<\/p>\n

La couleur de la coquille varie d’une teinte claire, blanch\u00e2tre, \u00e0 des tons sombres, gris\u00e2tres.
\nElle est ornement\u00e9e de reliefs, correspondant \u00e0 des c\u00f4tes longitudinales et des cordons spiral\u00e9s.<\/p>\n

Le corps de l’animal arbore quant \u00e0 lui une couleur blanc-jaun\u00e2tre et porte des mouchetures sombres.<\/p>\n

Il comporte un pied muni d’un opercule ovale permettant l’obturation de la coquille une fois l’animal r\u00e9tract\u00e9 \u00e0 l’int\u00e9rieur.<\/p>\n

  <\/p>\n

Le Buccin ond\u00e9 est un Gast\u00e9ropode pr\u00e9dateur, se nourrissant de vers (Ann\u00e9lides polych\u00e8tes notamment) et de Mollusques bivalves comme la Coque. Il provoque dans ce cas l’\u00e9cartement des valves en y introduisant le bord de sa coquille, avant d’ins\u00e9rer sa trompe dans l’ouverture. <\/p>\n

Son alimentation comporte \u00e9galement des cadavres en putr\u00e9faction (poissons, Crabes), qu’il rep\u00e8re par l’olfaction.<\/p>\n
