Hmm, interesting,

Quote:
"The research, published in Marine Pollution Bulletin, documented 24 species of octopus ... even carrying plastic items around while “stilt-walking” on two tentacles to conceal themselves from predators."

I've long suspected that the next species to gain intelligence and rule the world long after us talking apes are gone will be Octopi.

cephalopods (squid and octupi) are unusually smart for where they sit in the evolutionary tree

Some think they know why

In Jervis Bay, off Eastern Australia, researchers recently spotted 15 gloomy octopuses congregating, communicating, dwelling together, and even evicting each other from dens at a site the scientists named “Octlantis.” The international team of marine biologists, led by professor David Scheel of Alaska Pacific University, filmed these creatures exhibiting complex social behaviors that contradict the received wisdom that these cephalopods are loners. Their study was published in the journal Marine and Freshwater Behavior and Physiology (paywall).

Not bad for an invertebrate eh their closest relatives are molluscs - clams
Admittedly the cephalopds haven't changed much in the last 100-200 million years but they certainly are weird, smarter than....well you be the judge

I think a case can be made that they are smarter than the typical "Florida man" you read news articles about appearing before a judge.

I wouldn't anticipate it. The niche of 'ruling the world' has only existed for a few thousand years out of the several hundreds of millions that complex life has been around. An animal that lives like us might really be a rare anomaly considering even we didn't live like this for most of our existence.

That is of course a possibility. But octopi have predate humans, and who knows what descendants they might have.

Octupi have evolved quickly but are unable to evolve beyond their current niche due to competition from bigger critters that came after them.
