Thanks for the reply,
The Brown crab/edible crab seem to be out at sea so for the moment its shore crab

I was thinking of adding a small amount to Soup/CHowder/Stew etc,I saw lots of Razor Shells washed up but none intact,I think these are caught at very low tides,
Il keep looking around and see what else i can find,As far as i know you can eat those shellfish that stick to the rocks,Im not sure what they are called ,They are white and stick to rocks,They have a very strong shell and it takes a ,lot of effort to move them from the rocks
