"The cuttlebone is the skeleton of the cuttlefish, which is a member of the cephalopod family, and a cousin of the octupus and other squids. This lightweight internal shell helps the creatures stay afloat. Cuttlefish live for only a few years and die after breeding. Commercial fishermen harvest the cuttlefish primarily for food, and the skeleton is cut out during preparation."
Pealed this off a "Pacific American Singer newsletter"
but ya. Cuttlebone is the bones,head,spine of a dead cuttlefish.
