Mysterious Deep-Sea Shark Captured On Camera By Scientists

Using a camera to probe the sea floor, scientists documented a mysterious deep-sea shark twice in two days near California’s Channel Islands.

A group of scientists with the Exploration Vessel (E/V) Nautilus saw two blunt-nosed six-gill sharks, one a bit smaller than the other, at depths of 700 feet and 1,000 feet last Monday. An ROV, or a “remotely operated underwater vehicle,” named Hercules was used to record the sharks. During the second shark encounter at Santa Cruz Island, a giant crab stole the show when it sauntered into camera view. It toted another crab in its claws.

E/V Nautilus uploaded the video to their YouTube channel. “Is that a taxicrab?” quipped one of the scientists in the video. “It’s an Uber crab,” another scientist replied.

“Within two days, ROV Hercules encountered two bluntnose sixgill sharks while exploring Channel Islands National Marine Sanctuary,” read the video caption. “This second shark was spotted off Santa Cruz Island at 306m (1,000ft) depth, and appears to be smaller in size than the first shark spotted. The green scaling lasers seen in this video are set at exactly 10 cm apart.”

Sixgill sharks are expected to grow to up to 18 feet and are named for the six gill openings on each side of their heads. Most other shark species five gill slits instead.

Considered prehistoric-looking, these sharks resembled a fossil shark species that existed 200 million years ago. They’re not well researched because they usually inhabit ocean depths of 600 to 3,000-plus feet. To survive, sixgill sharks preyed mostly on fish, smaller sharks, crabs, squid, seals and rays.

As the E/V Nautilus video shows, these sharks moved slowly. However, they possessed a certain poise as they navigated the lightless ocean depths.
