Cephalopods

I'm a huge fan of Cephalopods, if you don't know what that means, it simply refers to underwater critters like Octopus, Cuttlefish, Squids & of course the Nautilus, they are the most intelligent members of the super class we refer to as Invertebrates which includes insects, crabs, lobsters, snails, clams, octopuses, starfish, sea-urchins and worms. Actually on planet Earth a vast majority of animal species are invertebrates, some estimates put the figure at around 97%. So that is why the category is not Invertebrate's, I'll stick with an easier managed category like Cephalopods and see what photos I can get of them.
