Octopus Fight

This appears to be a scuffle between two octopuses over a nice cozy place to sit. You see provocation, chase, and some smacking about, plus a bit of color-changing, which might be communication, a cooling-off, or bragging. Who knows? There’s also an intriguing bit where the octopus wipes itself down. I can’t even tell who won, because how do you tell one shapeshifter from another? Anyway, it’s a pretty cool sequence. This all happened off the coast of Asu Island in Indonesia. (via Metafilter)
