A team of scientists from the University of Western Australia and Japan recorded lip slugs at a depth of 8,336 meters near Japan, and older records are also held by other lip slugs, but at a depth of 8,178 meters in the Mariana Trench in the Pacific Ocean.

In September 2022, the research vessel DSSV Pressure Drop embarked on a two-month expedition to the deep ocean trench around Japan in the North Pacific Ocean. The mission is to explore the Japan Trench, the Izu-Ogasawara Trench and the Ryukyu Trench at depths of 8,000 meters, 9,300 meters, and 7,300 meters, respectively. The expedition was part of a 10-year study of the world’s deepest fish population.
University of Western Australia (UWA) Professor Alan Jamieson, founder of the Minderoo-UWA Deep Sea Research Center and lead scientist on the expedition, worked with colleagues at Tokyo Marine Science and Technology University to install the decoy camera system at the deepest point of the trenches.
In the Izu-Ogasawara Trench in southern Japan, the team recorded a fish of the genus Facial powdersurname Lizard (or family of slugfish), swimming at a record depth of 8,336 metres. Scientists don’t know exactly what species it belongs to.
A few days later, in the Japan Trench, the team caught two fish from a trap at a depth of 8,022 meters.they belong to species whitefly And it was the first fish caught from a depth of more than 8,000 meters. In 2008, they were only found at a depth of 7,703 meters.

“The trenches in Japan are amazing places to explore. We’ve spent over 15 years studying these fish. Lizard this. There’s a lot more to them than just depth, but the maximum depth they can survive is really impressive,” commented Jamieson.
The new record-setting individual is still immature and smaller.fish Lizard As juveniles live deeper in their depth range, they tend to fight other deep sea fish.
“For me, the real message doesn’t have to be the fish Lizard live at a depth of 8,336 meters, but we have enough environmental information to predict that these trenches are home to the deepest fish. In fact, no one had seen or caught fish from this trench before the new expedition,” Jamieson said.
