Welcome to TONMO and I hope you enjoy the site. Cephalopods are wonderfully fascinating creatures and it's great that you are willing to contribute to the forums.
However, I'm sure some of us are a little confused by one or two of your posts so in future please could you be a little more specific when starting up a new topic. Octopuses are, after all, a vast subject.
What aspect of cephalopods interests you particularly?
