A friend has a second hobby, I go out to sea with him to catch lobsters on Saturday's. This is his catch of the day. This blue beauty was "catch and release" of the coast of Ma. Marblehead area. I would say light Cobalt or Saphire Blue. Can you see the crease down the middle of the back ? That is where they molt and seperate there shell. When they are done molting they come back Blue again. Enjoy
