This is what a snail basket looks like when the snail has finished eating a mussel. The small
mussel is open and empty.
Often, the snails drill a mussel and eat everything but the muscles and foot. You can see the
posterior adductor muscle below the borehole in this small mussel.
This is a posterior view of the eaten small mussel. You can clearly see
the white posterior adductor muscle! That is the main muscle that holds
the two valves (shells) of the mussel together.
These are the computers that control the pH of my treatments.
