Footage from a Blackwater Dive Off the Coast of Italy Frames the Striking Marine Creatures Found in Its Depths
For marine biologists and photographers, a nighttime dive into the ocean offers an austere backdrop for capturing the myriad creatures that live below the surface: entirely devoid of light, black water creates a stark visual contrast to the iridescent, translucent, and tentacled organisms that float in the dark expanses, making rare sightings of cusk eels and or billowing blanket octopuses all the more striking. An expedition by Alexander Semenov (previously) near Ponza Island unveiled an array of marine life off the western coast of Italy, framing their unique forms and movements. The footage is part of an ongoing documentary project for Aquatilis, and you can see more from Semenov on his site.

On a 34-day expedition around the Phoenix Islands Archipelago, marine scientists from the Schmidt Ocean Institute captured exceptionally rare footage of the elusive glass octopus. With a speckled, iridescent membrane, the aquatic animal is almost entirely transparent—only its optic nerve, eyes, and digestive tract are visible to humans—and sightings like these are so infrequent that scientists previously resorted to studying the species only after pulling it from the stomachs of its predators.
Along with successfully capturing this footage, the research team also identified new marine organisms and recorded the sought-after whale shark swimming through the Pacific Ocean during the expedition. For similar underwater reveals, check out a blanket octopus unveiling her membrane.
