Angry Octopus

Check out all the things this octopus does. It controls the water underneath its membranes to appear inflated at times. That's the biggest thing you'll notice in this video, but there's more. It changes color, from purple to pink to blue and back to purple again, with orange highlights and white spots at times. The octopus also appears to have spikes on its head, but that's more of a disguise. As it swims away, its head is smooth! If you watched this video a few more times, you'll probably find some other amazing power. What's happening is that the octopus was not happy with the presence of the videographer, and was warning her off. You can read the story at Pink Tank Scuba. (via Everlasting Blort)
