| If you look at the shell of a dead animal, the side that is stuck to the surface usually has a hole in it. The animal secretes byssus threads through this hole to stick to surface. Initially, this opening is a notch on the edge of the shell. But as the animal grows and secretes more shell material, the notch is surrounded and becomes a hole. |
 Notch in one of the valves is clearly seen in the shell of this dead animal Pulau Sekudu, Jun 06 |
