Scientists have set a world record by videotaping a fish at record-breaking depths. In this respect informs University of Western Australia.
In September 2022, the research vessel DSSV Pressure Drop made a two-month expedition to deep-sea trenches around Japan in the North Pacific. The task was to explore the Japan Trench, Izu-Ogasawara Trench and the Ryukyu Trench at depths of 8,000 m, 9,300 m and 7,300 m respectively.
As part of this work, biologists were able to film a representative of an unknown species of the slug genus (pseudoliparis). The observation was made at a depth of 8336, the world record for fish observation. Juvenile sea snails, unlike other deep-sea fish, live deeper than adults.
A few days later, in the Japan Trench, the team caught two fish in traps at a depth of 8,022 meters. These individuals belonged to a known slug species. Pseudoliparis belyaevibefore that, the maximum depth of their detection was 7703 meters.
Previously, scientists found that female spiders fake dead so male partners aren’t afraid of being beaten.
