Amazing to consider how different these molluscs are from humans, and yet how these creatures more closely related to clams exhibit intelligence similar to highly intelligent vertebrates such as apes, crows, and dolphins.
Interestingly, another Gizmodo story discusses the recent discovery that one species of octopus seems to be forming rudimentary societies, akin to villages. Octopolis and 'Octopus Atlantis' have been found off the coast of Australia where the Moody Octopus may be plotting to take over the world from we landlubbers (so speculates Gizmodo).
When I see them invading, I'll worry.
Thanks!
