Here's a video of a snatch-and-grab robbery by an octopus, who steals a digital camera, which continues to shoot video as the creature swims away with it!
The photographer who posted this underwater footage on YouTube writes: "I didn't feel threatened at all during the whole ordeal. he seemed to be fixated on the shiny metallic blue digital camera. the only confusing behavior was how he dashed off with it like a thief haha. cheeky octopus."
