Very cool!
I've always found octopi fascinating.
My favorite story is the one of the octopus in a tank across the room from a tank full of crabs, both tanks with a cover to prevent excapes.
A mystery unfolded when the workers arrived one morning to find a crab missing, just shell-bits remaining. They verified that both tanks were securely closed, but the same thing happend the next day.
Finally, they set up a camera pointed at the two tanks. When the film was reviewed, they witnessed the octopus squeezing throug a tiny gap to escpae his tank, crawling over and into the crab tank, helping himselft to dinner, then returning "home" with a full tummy!
Smart and weird!
