If ever there were a video that makes us glad we're safe on our sofa and not floating in the ocean, this would be it. News.com.au reports the clip comes out of the Sea of Japan, where a Russian scuba diver swimming around the Garrow Peninsula is witnessed having a close encounter with a giant octopus. And by "close encounter," we mean the octopus can be seen in the video literally latching onto the diver, who's flanked by at least two other divers during the incident. The attack doesn't last long: After the diver glances over his shoulder, spots the octopus, and makes a few more kicks with his fins, the octopus suddenly detaches and retreats to the seafloor.
Giant octopuses, which are typically found in the cooler waters around Japan, Russia, and the Pacific Northwest, usually stay away from humans. Some sources note that the largest one ever weighed in at around 600 pounds, though Stuff says the official record documented by Guinness has it at about half that poundage. After the octopus has given up and the heart-stopping moment is over, the video offers us a cool scene: the creature changes color and pattern to blend in with the rocks it finds as a hiding spot.
