This video has gone viral on Facebook:I've posted the original by Thomas Marqué and not the uncredited FB version. The video looks real, very real, like a stressed out octopus someone threw on a beach. It looks so real that it initially fooled me and a number of other octopus experts. My (limited) understanding is that this CGI tool was used to create this very realistic animation (How to render using Mantra). Houdini is a great name for a program to render lifelike octopus animations! And is also the name of my first octopus!
