New research shows that the advantages of HDTV aren't lost on octopuses. A recent study on octopus behavior made the upgrade from CRT sets to HDTVs for the playback of octopus-related videos, like one of a tasty crab.
Whereas the octopuses had previously ignored the videos—researchers surmise that on the CRT sets the images were "incomplete and probably incoherent" when viewed by the octopuses—the HD crabs had the octopuses reacting like they were the real thing. Scientists had tried unsuccessfully for ten years to get octopuses to react to video, until the leap to HD got the creatures interested. Wait until they see Crabs in 3D. [New Scientist]
