I'll start being concerned when they evolve opposable thumbs.The linked article said:
They already have opposable arms, which enables them to do all the things that we can do with hands, like opening a bottle.
They have brains in their arms, to the point where a severed octopus arm will still hunt for food on its own and are pretty smart for something that we eat. In captivity, they'll sneak out of their tanks and steal fish to eat from other tanks and sneak back in.
When they develop lungs and crawl out onto dry land, I, for one, will welcome our new mollusk overlords.
)if I interpret you correctly, you assume that male squids are larger than females? I'm no expert on cephalopods but in most non-mammal species the female is taller. I'd have assumed that to be the case with squids, too.
JarodRussell wasn't referring to intelligence per se, but rather a species' ability to make tools and develop technology -- which, of necessity, would be extremely limited in an aquatic environment.
After all, they already have their in-built jet propulsion
