seen? This little clam is commonly seen stuck under stones
on many of our shores, sometimes a few clustered together. But it
is often overlooked as its 'hairy' shell camouflages it well.
Features: About 2.5cm long. The sturdy two-part shell is
oval with fine ribs. There is usually a layer of fine brown hairs
(called the periostracum) covering the shell. The hairs grow particularly
thickly towards the shell opening. The animal is usually firmly attached
to the underside of stones and rubble, usually with the shell opening
facing the hard surface.
