The Elusive Glass Octopus Finally Filmed In The Dark Depths Of The Pacific

The glass octopus was first discovered in 1918. These cephalopods remained mostly elusive and little was known about them except that the creatures frequent subtropical and tropical areas deep in the ocean mostly in the twilight zone (mesopelagic) which is between 656 and 3,280 feet (200-1,000 meters) below sea level, and also the midnight zone (bathypelagic) between 3,280 and 9,800 feet (1,000-3000 meters).
