A record has been set for the depth at which a fish has ever been photographed. Scientists have tracked it down as deep as 8336 meters below the water’s surface.

A new record breaker has been spotted in waters southeast of Japan. It was made by a Japanese-Australian scientific expedition studying the Izu-Ogasawara Trench. This is one of Earth’s oceanic trenches, or unusually large depressions in the ocean floor.

The Izu-Ogasawara ditch is as deep as 10 kilometers at its deepest point. The scientists, however, were not looking for fish that deep. They lowered their equipment — an unmanned vehicle with a boom and camera — to just over 8,300 meters.

Eight kilometers underwater, the pressure is as much as 800 times greater than on the surface. However, even there — as it turned out — there are fish living. A species belonging to Pseudoliparis took the bait. This is a genus of demersal fish that live in the greatest depths of the Pacific. They inhabit the so-called hadal zone, extending below 6 km underwater.

What does the world’s deepest living fish look like?
