I've heard that  octopuses  (whats the plural anyway? ) in particular are
extremely smart. I remember an experiment where they put a crab in a jar,
and put it in an octopus tank. The octopus of course got the crab (the lid
was off). Then they tried the experiment again, this time with the lid to
the jar screwed on. The octopus actually figured out how to open the jar.
I've heard that octopus can also learn by watching other octopus, how to
do that trick. Another thing was, they put Astro turf (a bristly plastic
carpet type stuff) on the rims of Octopus tanks so they dont crawl out of
their tanks to go exploring). Maybe in several million years we could have
sentient Octopuses? :)
