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).
