“This rarely seen glass octopus bared all recently — even a view of its innards — when an underwater robot filmed it gracefully soaring through the deep waters of the Central Pacific Ocean.”
Like other “glass” creatures, such as glass frogs and certain comb jellies, glass octopuses are almost completely transparent, with only their cylindrical eyes, optic nerve and digestive tract appearing opaque. The expedition crew reported two encounters with the glass octopus — an impressive count given that previously there was such limited footage of these clear cephalopods, scientists had to learn about them by studying chunks of them in the gut contents of their predators…
During the expedition, which ended July 8, a crew of marine scientists discovered a handful of what are likely newfound marine animals on nine previously unexplored submarine mountains known as seamounts. The team also completed high-resolution seafloor mapping of more than 11,500 square miles (30,000 square km) around the archipelago and video recordings of five additional seamounts filmed by the underwater robot SuBastian, according to a statement. SuBastian also snagged footage of a whale shark (the largest living fish in the world) and a long-legged crab stealing a fish from another crab.
The expedition sent SuBastian on 21 dives, enabling the robot to record more than 182 hours on the seafloor.
The expedition was run by the Schmidt Ocean Institute, a nonprofit operating foundation co-founded by Wendy and Eric Schmidt, the former CEO of Google.
