  <\/p>\n

L’\u0152illet de mer (Metridium senile<\/em>) est une An\u00e9mone de mer de la famille des Metridiid\u00e9s.
\nCe repr\u00e9sentant du groupe des Cnidaires et plus particuli\u00e8rement des Anthozoaires a fait l’objet de l’article de la semaine 25-2014<\/a>.<\/p>\n

  <\/p>\n

Le corps de l’\u0152illet de mer est form\u00e9 d’un disque basal et d’une colonne surmont\u00e9e de tentacules.
\nIls entourent un large disque oral lob\u00e9, au centre duquel s’ouvre la bouche, seul orifice de la cavit\u00e9 gastrovaculaire.<\/p>\n

  <\/p>\n

L’\u0152illet de mer est une esp\u00e8ce pr\u00e9datrice, \u00e0 l’instar des autres Cnidaires.
\nSon r\u00e9gime alimentaire est compos\u00e9 de petits crustac\u00e9s et des larves de divers animaux (vers, Mollusques, Ascidies, crustac\u00e9s). <\/p>\n

Elle en r\u00e9alise la capture \u00e0 l’aide de ses tentacules qui portent des cellules sp\u00e9cialis\u00e9es, les cnidocytes.
\nUrticantes, elles agissent comme des harpons au contact de proies potentielles.
\nUne fois immobilis\u00e9s, les animaux sont amen\u00e9s \u00e0 la bouche par les tentacules.<\/p>\n
