Cuttlefish are curious-- this one stayed around for a look at me, though it could have easily "jetted" away with its siphon. The safest position for it is just as seen here; since its siphon is pointed toward the threat (me), its direction of movement would be away from the camera. Cuttlefish can change colors faster than a television screen. Their "bones", the inner chitonous skeleton, often wash up on the beach, and are frequently sold in pet stores for parakeets and other birds to sharpen their beaks.
Identification: Sepia latimanus
