Rare footage shows a "Dumbo" octopus swimming near a submersible in the deep ocean. A still from the video shows the Dumbo octopus. Side by side images show the Dumbo octopus, captured more than 5,500 feet underground. This isn't the first enthralling deep-sea footage that the Ocean Exploration Trust has shared. The Ocean Exploration Trust livestreams its missions on a website for the Nautilus.
