Off the coast of Japan, scientists captured footage of the deepest fish ever caught.

Scientists film deepest ever fish on seabed off Japan

During a scientific expedition into the depths of the northern Pacific Ocean, a young snailfish reached a depth of 8,336 meters (over 27,000 feet), making it the deepest fish ever recorded.

On Sunday, footage of the snailfish that was captured by sea robots in deep trenches off the coast of Japan in September was made public by researchers from the University of Western Australia and the Tokyo University of Marine Science and Technology.

The scientists caught two additional snailfish at 8,022 meters, breaking another record for the deepest catch, in addition to filming the snailfish that was caught at the deepest depth.

In 2008, scientists found the deepest snailfish ever, at 7,703 meters, but they had never been able to collect fish from below 8,000 meters.

According to marine biologist Alan Jamieson, who founded the Minderoo-UWA Deep Sea Research Centre and was in charge of the expedition, “what is significant is that it shows how far a particular type of fish will descend in the ocean.”Set featured image

As part of a 10-year investigation into the world’s deepest fish populations, researchers are filming in the trenches off Japan. According to Jamieson, although the majority of snailfish belong to the family Liparidae, some can survive at some of the deepest depths ever recorded.
During the two-month review last year, three “landers” – programmed ocean robots fitted with high-goal cameras – were dropped into three channels – the Japan, Izu-Ogasawara and Ryukyu channels – at different profundities.

The footage showed the deepest snailfish calmly hovering alongside other crustaceans on the seabed in the Izu-Ogasawara trench.

Jamieson ordered the fish as an adolescent and said more youthful remote ocean snailfish frequently stay as profound as conceivable to try not to be eaten by greater hunters that swim at shallower profundities.

One more clasp took shots at somewhere in the range of 7,500 and 8,200 meters in a similar channel showed a state of fish and shellfish crunching at snare attached to an undersea robot.

Pictures of the two caught snailfish – distinguished as Pseudoliparis belyaevi – give an intriguing look at the novel elements that assist the remote ocean species with enduring the outrageous climate.

According to Jamieson, their lack of a swim bladder, which helps other fish float, works to their advantage. They also have tiny eyes and a translucent body.

According to the professor, the Pacific Ocean is particularly conducive to lively activity due to its warm southern current, which encourages marine life to go deeper and provides bottom feeders with a good source of food.
Jamieson stated that despite the fact that each lander alone costs $200,000 to assemble and operate, scientists want to learn more about creatures that live at extremely low depths.

He stated, “The challenges are that scientists don’t have a lot of money and technology has been expensive.”
