This oceanographic research expedition captured 2 footage of the glass octopus from a research vessel near the Phoenix Islands, which is an archipelago in the central Pacific Ocean, north of Samoa, part of the Republic of Kiribati. The islands are located over 3,200 miles (5,100 kilometers) to the northeast of Australia.
The glass octopus is similar in appearance to other glass-like creatures like some comb jellies, and glass frogs. The expedition encountered the obscure glass octopus twice in the course of their voyage.
