Bonnet Shell Limpet


Capulus ungaricus

This limpet is widespread from west Africa to northern Norway, although less common in the North Sea, in the sublittoral down to about 850m. It is occasionally found at the extreme low water mark. It is commonly found on stones and shells, particularly those of scallops and is a suspension feeder; it feeds on small particles within the water column. They are protandrous consecutive hermaphrodites, maturing as a male and then changing to a female, with breeding thought to occur in late spring.
