The solution to Bit-o-Critter round 24

Well that was quick; I guess I made it too easy.  Heather D guessed correctly that it was the beautiful Pyjama Squid, Sepioloidea lineolata.  These gorgeous little cephalopods hail from my home country of Australia, just like the wrasse in BoC 23b, which is still up for grabs.  I think technically pyjama squids are a cuttlefish because the eye is a slit not a round pupil and because the undulating fin runs the full margin of the hood.  I could be wrong, but thats what I was always taught.  Perhaps someone with more cephalopod knowledge can chime in here.
