It wasn't that long ago that Otto the octopus was bent on destroying the electrical system in his German aquarium. Now a cephalopod at the Santa Monica aquarium is following in his footsteps, flooding the building overnight with a few hundred gallons of seawater:
The suspected cephalopod weighs about a pound. Its head is about the size of a football and its tentacles are twice as long, aquarium spokeswoman Randi Parent said. "She's done this before, but this is the first time she's done it while no one was around."
Oh. . . so she's done this before. Nice.
Update: an interview with an octopus researcher at Sci Am, entitled "Are Octopuses Smart." (Yes is the answer.)
