Anybody who owns a canary probably knows about “cutt1ebone,” which comes from the cuttlefish. The cuttlebone is given to canaries and other cage birds so they can sharpen their beaks on it.

But,except for this, the cuttlefish is quite unknown to most of us. The cuttlefish is not a fish, but a mollusk. It belongs to the class of mollusks called “cephalopods,” which means “head-footed animals.” This is because of the arrangement of the arms, or feet, around the mouth. The Octopus also belongs to this class of mollusk.
