You'll see more than one octopus here, but you should know that the pink one is a ringer. It's a robotic octopus sent to study and film deep sea life. The question that's never really addressed is who is filming the robot? Anyway, the real action comes from a coconut octopus, who lives in a coconut husk. When he goes out, he takes his husk with him, and collects other useful things like seashells and trash. He only leaves his coconut husk long enough to chase down some lunch and get into a fight with another coconut octopus. Meanwhile, we see him (or her) change size, shape, and even color. We see him walking around on his tentacles, carrying his husk, until swimming proves more effective. He seems quite antisocial with the other coconut octopus, but he apparently feels some affection of sorts for his pink robot friend. At least the robot isn't trying to attack him. This scene is from the BBC series Spy in the Ocean. -via Born in Space
