La Gibbule ombiliqu\u00e9e (Gibbula umbilicalis<\/em>) est un Mollusque gast\u00e9ropode marin appartenant \u00e0 la famille des Trochid\u00e9s.<\/p>\n

Cette esp\u00e8ce est pr\u00e9sente en milieux rocheux et abrit\u00e9, dans la zone intertidale alternativement couverte et d\u00e9couverte par la mar\u00e9e, jusqu’\u00e0 une profondeur de vingt m\u00e8tres environ.
\nElle \u00e9volue parmi les algues (Fucus, Ascophylle) mais, supportant les variations de temp\u00e9rature et de salinit\u00e9, elle est \u00e9galement abondante dans les cuvettes \u00e0 mar\u00e9e basse.<\/p>\n

  <\/p>\n

La Gibbule ombiliqu\u00e9e est ais\u00e9ment identifi\u00e9e aux particularit\u00e9s de sa coquille.<\/p>\n

Pouvant atteindre une hauteur de 16 mm pour un diam\u00e8tre de 22 mm, celle-ci est spiral\u00e9e et fr\u00e9quemment \u00e9rod\u00e9e \u00e0 son sommet.
\nChez l’adulte<\/a>, elle compte jusqu’\u00e0 sept tours de spire, le dernier \u00e9tant particuli\u00e8rement d\u00e9velopp\u00e9.<\/p>\n

La coquille porte des stries, et est color\u00e9e en gris, vert, ou jaune. Elle est orn\u00e9e de larges bandes transversales de couleur violette ou orange, formant des ondulations au niveau des sutures.<\/p>\n

Au contact du substrat, son axe est mat\u00e9rialis\u00e9 par un orifice marqu\u00e9, l’ombilic.
\nL’ouverture par laquelle \u00e9mergent la t\u00eate et le pied est de forme circulaire. Elle laisse appara\u00eetre la nacre dont est couverte sa face interne, et peut \u00eatre obtur\u00e9e par un opercule corn\u00e9. <\/p>\n
