South of Tasmania, hundreds of undersea mountains mark the deep ocean floor. Now, a monthlong survey of these seamounts in and around Australia’s Huon and Tasman Fracture marine parks has revealed a spectacular range of deep-sea species, from feathery corals and tulip-shaped glass sponges to bioluminescent squids and ghost sharks. The survey team has also uncovered more than 100 previously unnamed species that are likely new to science.

It felt a lot like a moon landing to the researchers who experienced it—descending thousands of feet below the surface of the ocean into complete darkness. Ambient ocean light extends down only about 600 feet. After that, no amount of straining your eyes will help you see through the inky blackness.

Scientist Tim Shank and photographer Luis Lamar were descending into Lydonia canyon, one of several among the canyons and underwater mountains sitting 130 miles from Massachusetts, when they were slowly surrounded by darkness.

With oil exploration looming on the horizon for the Great Australian Bight, stakeholders felt it was an important time to learn more about the species that call the rough waters off Australia’s southern coastline home.

A rarely seen shark embryo. Corals up to 7 feet (2 meters) high. Sponges with sharp edges.

These were among the hundreds of findings reported by U.S.  who have wrapped up a 22-day mission exploring waters around Puerto Rico and the U.S. Virgin Islands in the deepest dives ever recorded in the region. Guided by other land-based scientists watching live feeds, they collected 89 samples and will now start to analyze them, Daniel Wagner, expedition coordinator with the U.S. National Oceanic and Atmospheric Administration, told The Associated Press on Wednesday.

The deep sea is a mysterious world, pitch black and subject to extreme conditions. Life there is specially adapted to this environment, but also remarkably susceptible to human activities such as fishing.

Deep-sea fish tend to be slow-growing, late-maturing and long-lived. Because of these factors, stocks can be quick to collapse and slow to recover. Their sensitive and vulnerable nature makes ending over-exploitation of vital importance.

An enormous shark ”nursery” swarming with the predatory fish and strewn with their eggs has been found in the waters 200 miles off the western Irish coast.

The rare discovery was made by a remotely operated vehicle exploring the region’s cold-water coral reefs at depths of around 750m.

Scientists observed a large school of blackmouth catsharks, a relatively small species found throughout the northeast Atlantic, alongside the more unusual and solitary sailfin roughshark.

When Luiz Rocha, a fish biologist at the California Academy of Sciences, goes scuba diving, he tacks on one and a half times his body weight in specialized diving gear. Once he submerges, he can’t spare a moment to take in the vibrant corals just beneath the surface — he has greater depths to plumb.

Rocha is headed toward what Smithsonian Institution fish biologist Carole Baldwin calls “a very diverse and productive portion of the tropical ocean that science has largely missed”: mesophotic reefs. “Mesophotic” is Greek for “middle light,” referring to the intermediate amount of sunlight that can penetrate to depths of 30 to 150 meters (100 to 500 feet) below the ocean’s surface.

Most people are familiar with the ever-popular capelin or cod, but get up close and personal with three fish with creepy names and faces only a mother (fish?) could love.

Jane Adey, host of The Broadcast, got a peek in a Department of Fisheries and Oceans lab in St. John’s.

The deep sea angler is also known (more nefariously) as the northern sea devil.

Their squat bodies actually come in handy for their living conditions — this one was found 1,400 metres below the surface, according to Karen Dwyer, a fishery biologist with the Department of Fisheries and Oceans in St. John’s.
