CONT

Le pétoncle des roches est un gros coquillage massif dont la coquille peut atteindre une hauteur de 250 mm (de la charnière au bord de la valve supérieure). La forme des valves est très irrégulière, et la surface extérieure est creusée de grosses côtes rayonnantes, de couleur brun, gris et vert. […] À l'intérieur, la zone proche de la charnière est de couleur pourpre foncé. Au début de leur existence, les petits pétoncles des roches ont une phase de vie libre, et se déplacent comme les autres espèces mais, lorsqu'ils atteignent environ 25 mm, ils se fixent sur un rocher et y restent toute leur existence.

OBS

Hinnites giganteus; Hinnites multirugosus : synonymes non acceptés selon certains auteurs.
