Pulling mussels from the shell

This is pic of The Scallop, a sculpture on the beach here in Aldeburgh as a tribute to composer Benjamin Britten, who lived here.
This pic is from early morning run. See extra for one from later on in the day.
We then drove up coast to Southwold, pretty but extremely busy.

Not the right shellfish, but you get the idea:
