Would you just look at him? Sprung to life out of a Pixar movie, the ghostly little fella pictured above was discovered last month by Deep Discoverer, the deep-diving robot that travels with NOAA’s Okeanos Explorer. Spotted 4,290 meters beneath the surface, it’s the deepest observation of a so-called incirrate octopus ever, and it might be a new species.
