Is it octopus, octopuses, or octopi? Whatever the proper plural (the Oxford dictionary suggests octopodes as correct), the intelligence they’ve displayed is fascinating. It makes you wonder whether they would consider that we are intelligent from the evidence they’ve seen.
Isn’t it intelligent to try to escape captivity?
Nakase said that on each of its three escape attempts, the octopus had to climb out of its tank on the second level of a shelving unit and scramble down two shelves to get to the floor. On one occasion the octopus was found next to a drain on the floor, 15 feet from its tank.
Simon said if not detected, the octopus could have successfully escaped from the facility to rejoin its kind in the sea.
“REEF has a flow-through sea water system installed,” Simon said. “If the octopus had found its way into that, it could have easily escaped back into the waters at Campus Point.”
And here’s a recent article on how they can make their own homes out of coconuts. And I can’t help thinking that I really should follow the article’s suggestion and sculpt an octopus purse to start the trend 
Next, we’ll find that sea sponges really do live in pineapples. And I’d be fine with that, as long as they don’t have Sponge Bob’s hideously annoying laugh
