Cephalopods

Time for my blue-moon post! Ya know, cause I hardly post here. Shame, really...

Anyway I figured I'd bring up a thread about one of the most curious group of marine animals, the Cephalopods. I know that some people do keep Octopi as pets, usually sold as Assorted Octopus. I also know that they usually don't live very long. Most species have a lifespan of a few years. I think even larger species only live about five years.

But what about Squid? And Cuttlefish? I know I heard of Cuttlefish being kept before, but not very often. What about squids?

Let this be a thread for open discussion about these critters.
