Deep-sea snailfish make history as the deepest fish ever filmed, reaching an incredible 8,336 meters below the surface in the Japan Trench. A team of researchers from the University of Western Australia and Tokyo University of Marine Science and Technology captured this remarkable footage using advanced sea robots equipped with high-resolution cameras.
The discovery not only sets a new record for the deepest fish ever filmed but also sheds light on the behavior of deep-sea snailfish, members of the Liparidae family. While most snailfish inhabit shallow waters, certain species have adapted to survive in some of the darkest and most extreme environments on the planet.
The two landers used by the researchers were deployed in three trenches – Japan, Izu-Ogasawara, and Ryukyu – at varying depths during a two-month survey last year. The footage revealed stunning images of snailfish hovering alongside crustaceans on the seabed, providing valuable insights into their unique adaptations.
Scientists identified one of the captured snailfish as Pseudoliparis belyaevi, characterized by tiny eyes, a translucent body, and an absence of swim bladder – features that enable it to thrive in the extreme conditions. The lack of buoyancy allows the fish to settle on the seabed without drifting upwards.
The discovery was part of a 10-year study into deep-sea fish populations, which aims to explore the world's most extreme environments. However, funding constraints remain a significant challenge for researchers, with each lander costing around $200,000 to assemble and operate.
As Professor Alan Jamieson, leader of the Minderoo-UWA Deep Sea Research Centre, emphasized, "The challenges are that technology has been expensive and scientists don’t have a lot of money." Despite these constraints, the research team remains committed to pushing the boundaries of human knowledge and understanding about life on our planet.
