Living in an essentially zero-gravity environment, many deep-sea animals have evolved soft, gelatinous bodies and collect food using elaborate mucus filters. Until now, studying these delicate structures has been virtually impossible. A new study published in the journal Nature describes a unique laser-based system for constructing 3-D models of diaphanous marine animals and the mucus structures they secrete.

Thanks to the Schmidt Ocean Institute, we’re getting a whole new perspective on life in the deep sea. After exploring the depths of the Indian Sea, they’ve released 4K footage of the Ningaloo Canyons. Located off the western coast of Australia, this previously unvisited area is the location of the institute’s latest expeditions—and the findings are incredible.

The canyons were visited by the ROV Sebastian, an underwater remotely operated vehicle which can go as far as 14,750 feet underwater. This far deeper than any human could ever dive, and the ROV can also stay at that depth far longer than any human-operated vehicle. Thanks to this technology, we’re able to stay on land and see the wonders far below the sea.

In the dark depths of the ocean, pretty much the only sources of light are the animals that live there. Whether flashing, glimmering, or emitting glowing liquids, many deep-sea animals are able to produce light (bioluminesce). MBARI researchers recently found that animals that live on the seafloor are much less likely to produce light than those swimming or drifting in the “midwater.”

Dean Grubbs thinks great white sharks are boring.

The veteran shark scientist, who has researched different shark species for 30 years, is vastly more intrigued by the little-seen dominant predator of the deep, dark, tropical and temperate oceans: the sixgill shark (most sharks have five gills).

A team of researchers stumbled upon a “whale fall,” a carcass of a baleen whale, during a live-streamed deep-sea dive. Incredible video shows a wide variety of sea creatures feasting on it.

The deep, cold waters off the rocky coast of Point Sur, California, are home to an unexpected community of organisms that most people associate with tropical settings—corals. Scientist Charlie Boch and his colleagues recently compared different methods to restore deep-sea coral by transplanting live coral fragments and measuring their survival rates. The experiment was conducted on Sur Ridge, 60 kilometers (37 miles) offshore and 800 to 1,300 meters (2,624 to 4,265 feet) below the ocean’s surface.

Deep sea biologist Diva Amon is a Trinidadian who was raised by the shore of the Caribbean Sea, but has become well known not for the sea’s edge, but rather for what lies deep beneath it. She co-founded SpeSeas, a non-profit NGO focused on increasing marine science, education and advocacy in Trinidad and Tobago, and is currently a Research Fellow at the National History Museum, London.
