The rarely seen glass octopus was captured on camera by an underwater robot in the deep waters of the Central Pacific Ocean.
The elusive and mesmerizing creature was seen during a 34-day expedition off the remote Phoenix Islands, 3,200 miles northeast of Sydney, Australia.
Glass octopuses are almost completely transparent, with only their cylindrical eyes, optic nerve and digestive tract appearing opaque. Little is known about them because they live in the twilight or midnight zones, 656 to 9,800 feet below the surface.
The glass octopus was spotted by a crew aboard the research vessel Falkor, which is run by the Schmidt Ocean Institute, a nonprofit foundation co-founded by Wendy and Eric Schmidt, the former CEO of Google.
