monacha (da Costa) by Gordon Fletcher.
The soft body of the animal covers part of the
lower surface of the shell, leaving only part of the ribbed shell
visible. The shell bears three darker spots, which are characteristic of
the species. Only one of these spots can be seen clearly in this photo, on
the forward part of the shell, above the animals siphon.
