Best things come when you least expect 'em!

Diving shallow today off Selsey I was in the act of changing a mooring chain
for a local fisherman. As I thrunged around heaving the old chain around and
stirring up a poor viz, a cuttlefish (Sepia officinalis?) hove into view
right next to me. Looked at me for a while then shot off. Made my dive.
After work I proceeded to collect a number of oysters (Ostrea edulis)from
around the mooring. Gave them to the fisherman as I am not fond of them.
Coming ashore some of the older fisherman lags pontificated about oysters
and metal. I found mine on the sea bed away from any metal/chains. Safe to
eat???
