   1. (Zool.) A cephalopod of the genus Sepia, having an
      internal shell, large eyes, and ten arms furnished with
      denticulated suckers, by means of which it secures its
      prey. The name is sometimes applied to dibranchiate
      cephalopods generally.
      [1913 Webster]

   Note: It has an ink bag, opening into the siphon, from which,
         when pursued, it throws out a dark liquid that clouds
         the water, enabling it to escape observation.
         [1913 Webster]

   2. A foul-mouthed fellow. "An you play the saucy cuttle with
      me." --Shak.
