I found a few elemental websites about Cephlapods that are of interest. The links in
BOLD are the most informative, the rest are excellent pictures.
A word of caution: The beautiful
Blue Ringed Octopus pictured in some of these links, looks like the perfect Cephlapod for the Home Aquarium because of it's coloring and very small size,
IT IS NOT!
It is one of the most venemous and toxic creatures in the sea. It's bite will kill an adult person very quickly unless anti-venin (which is not available outside of large Public Aquariums) is injected quickly. Leave this one to the Professionals!
