This is some remarkable footage from the remotely operated underwater vehicle Hercules of a sperm whale that comes to investigate the bot off the coast of Louisiana. The robot is about 2,000 feet down at the time of the encounter, significantly shallower than a typical sperm whale dive (around 4,000 feet) and nowhere near their max depth (over 10,500 feet). Could you imagine being able to hold your breath for an hour and dive TWO MILES? I don't even feel comfortable doing a pencil off the low dive.
Keep going for the video, complete with live commentary, which isn't necessarily a bonus.
Thanks to Joseph, who's convinced that whale knows the location of Atlantis.
