Rare glimpse into the depths: Scientists capture record-breaking fish in Japan Trench
A team of researchers from the University of Western Australia and Tokyo University of Marine Science and Technology has made history by filming a young snailfish hovering at an astonishing depth of 8,336 meters - the deepest ever recorded by humans. The remarkable footage provides valuable insights into the lives of these deep-sea creatures.
The incredible feat was accomplished using "landers" - automatic sea robots fitted with high-resolution cameras - that were dropped into three trenches in the Japan Trench. The expedition, which took place over two months last year, aimed to study the deepest fish populations in the world. Snailfish, members of the Liparidae family, are known to inhabit shallow waters but some species have adapted to survive at extreme depths.
The scientists captured footage of the young snailfish alongside other crustaceans on the seabed in the Izu-Ogasawara trench. According to marine biologist Alan Jamieson, the fish's behavior is crucial to understanding how deep-sea creatures thrive. "What is significant is that it shows how far a particular type of fish will descend in the ocean," he explained.
The two captured snailfish - identified as Pseudoliparis belyaevi - exhibit unique features such as tiny eyes, translucent bodies, and a lack of swim bladder, which helps other fish float. This adaptation is essential for surviving in the extreme environment of the deep sea.
While the discovery is remarkable, it highlights the challenges faced by scientists when studying creatures at such great depths. The cost of assembling and operating each lander alone is around $200,000, making further research a significant undertaking. "The challenges are that technology has been expensive and scientists donโt have a lot of money," Jamieson noted.
This groundbreaking expedition marks an exciting step forward in our understanding of life at the extremes of the ocean. The Pacific Ocean's warm southern current and abundant marine life provide an ideal environment for bottom feeders like snailfish to thrive, while also making them vulnerable to predators that inhabit shallower depths.
