Just to get the words right, cuttlefish and squid ain't the same thing - they are of different taxonomic orders.

Also, the largest cuttlefish (the Giant Australian) gets about a meter long, so I'd hesitate putting it up against a whale of any sort. But there's® some breeds of squid I would not want to meet in a dark alley.

Also also, have to echo Helen's support for eating both beasts. In Sardinia, cuttlefish are called sepia, and are eaten cooked in their own ink - absolutely delish, don't you think, Bean?

Also³, from now on, when I've a question about cephalopods, I'll be sure to consult an astrophysicist.
