The recording makes a strong case for Pseudoliparis being the deepest-ever fish. Though another fish has been reported from greater depths, the reliability of this record has been questioned. 'In other trenches such as the Mariana Trench, we were finding them at increasingly deeper depths just creeping over that 8,000-metre mark in fewer and fewer numbers, but around Japan they are really quite abundant.' Professor Alan Jamieson, the chief scientist of the expedition, says, 'We have spent over 15 years researching these deep snailfish there is so much more to them than simply the depth, but the maximum depth they can survive is truly astonishing.' This is 158 metres deeper than a previous recording made by the team in 2017, and close to the depth limit for all fish. Japanese and Australian researchers filmed a Pseudoliparis snailfish at 8,336 metres down as part of an expedition to some of the world's deepest ocean trenches. The discovery of the mysterious deep-sea creature breaks the record previously held by snailfish discovered in the Mariana Trench, the planet’s deepest point in the Pacific Ocean: One in 2017 of 26,831 feet (8,178 meters), beating the previous record by over 518 feet, and another in 2014 of a snailfish filmed at a depth of 26,716 feet (8,143 meters) by an expedition team led by University of Hawaii marine scientists.A fish found off the coast of Japan could be the deepest ever recorded. The expedition began last September to explore the deep trenches around Japan in the north Pacific Ocean. In previous expeditions, the snailfish has only ever been seen at a depth of 25,272 feet (7,703 meters) in 2008, it added. These snailfish were the first fish to be collected from depths greater than 26,247 feet (8,000 meters), the statement said. “In other trenches such as the Mariana Trench, we were finding them at increasingly deeper depths just creeping over that 8,000m mark in fewer and fewer numbers, but around Japan they are really quite abundant,” Jamieson said. It wasn't immediately clear how big the fish were. In remarkable footage released Sunday, a number of translucent, scaleless fish with winglike fins and eel-like tails can be seen swimming in a black abyss, illuminated by a spotlight cast from a baited camera. University of Western Australia and Japan Snailfish caught at depths of around 8,000 meters in a trench off Japan in the Pacific Ocean. “We have spent over 15 years researching these deep snailfish there is so much more to them than simply the depth, but the maximum depth they can survive is truly astonishing,” Alan Jamieson, the director of the Minderoo-UWA Deep Sea Research Centre, said in a statement Monday.ĭays after the fish were filmed, the team collected two snailfish ( Pseudoliparis belyaevi) in traps set 26,319 feet (8,022 meters) deep in the Izu-Ogasawara Trench. The record-breaking discovery was part of a decadelong study into the world’s deepest fish populations that was carried out by the University of Western Australia and the Tokyo University of Marine Science and Technology. They were found in the Izu-Ogasawara Trench south of Japan during a two-month voyage by a joint Australian-Japanese scientific expedition. The snailfish - of the genus Pseudoliparis, which resemble a ghoulishly large tadpole - was a small juvenile that has greater capabilities of living at such depths, the opposite of other deep-sea fish.
