“Gloomy octopuses (Octopus tetricus) reacted to films shown on liquid crystal high definition television (HDTV) as if they were seeing the real thing, according to a new study by Renata Pronk at Macquarie University in Sydney, Australia, and colleagues. "They lunge forwards to attack crabs and back off from other octopuses, much as they do in the wild," says Hanlon
