[Discussion of the remarkable abilities & intelligence of octopuses, despite being small, fragile, asocial beings.
With hundreds of millions of neurons (most in its arms, which appear to be able to think and act independently, coordinating with the other arms/mouth, with their immensely-strong suckers), octopus are able to recognize individuals and bear grudges (squirting water at the foe), somehow imitate color despite being color-blind, use tools, solve puzzles, and manipulate rocks to create shelters, they are noted escape artists: one octopus was found breaking out of its aquarium at night to feast in other tanks, sneaking back before humans returned.]
