One experiment trained an octopus to unscrew a jar with a fish in it by placing the cap real loose at first and slowly tightening it over a period of time. Then they set up a separate tank with several octos and several jars with fish and all the octopuses were starving and pissed that they could see the food and couldn't get at it. Then the trained octopus was given a jar and he unscrewed it and gobbled up the fish. All the other octopuses saw him do it and immediately did the same and got theirs. They're some smart bastards. They may even be self-aware.
