Description
This large snail has a shell with 6 to 8 rounded windings. At the front side the
animal has a kind of trunk, that is called siphon. Below this siphon, just
before the gills you can find its smelling organ. It often lives buried in the
sand or mud, with only the siphon sticking out. At the back of its foot, you can
see a small plate (operculum) that is used to close the shell. The eggs
are laid in a capsule, with a diameter of about 10 mm. Many capsules are laid together in a
spongy lump, the size of a fist. The young whelks that develop quickest, will eat the slower ones. The numbers
that survive are rather small, from more then 1000 eggs in a lump, only a few
will hatch. They are eaten in several countries.
