A team of researchers searching for the wreckage of a lost World War II destroyer in the Philippine Sea has returned to land, perhaps with even more exciting discoveries: the deepest swimming squid video ever recorded. evidence.
Cruising 20,300 feet (6,200 meters) just above the floor of the Philippine Trench, the young Magnapinna pacifica (Maganapinna pacifica) quickly became a record holder. Another Mizuhiki squid swam about 15,400 feet (4,700 feet), blowing off the previous champion. m) Under the Pacific Ocean, from the water.
Researchers also recorded four circular octopuses — well known as Dumbo. octopus For fins that resemble elephant ears, at the same depth, the team wrote in a recent study. According to study co-author Michael Vecchione, this is the second time Dumbo has been observed so deeply, and previous observations of floppy finned cephalopods in the Sunda Trench were not just a fluke. Prove that.
“This dive has multiple types Cephalopods At least you can live in the upper part of these really deep trenches, “Vecchione, a zoologist at the National Oceanic and Atmospheric Administration (NOAA), a cephalopod curator at the Smithsonian Castle in Washington, DC, emailed Live Science. Told.
Witness information also raises some questions. Atmospheric pressure can be up to 600 times higher, for example, “Magnapinna pacifica can live physiologically at depths of 3,200 to 19,600 feet (1000 to 6000 m).” The surface of the sea.
Researchers discovered the Big Fin in March 2021 while searching the wreck of USS Johnston, a US Navy destroyer that sank in 1944 during the Battle of Leyte Gulf.Manned submersible DSV limit factor (same type of submersible as Explorer) is used Use Victor Vescobo Go down to the bottom of Mariana Trench (June 2020), researchers filmed a dive to the bottom of the Philippine Trench, where they explored for more than four hours.
The team found a magnapinna pacificus just above the seabed. The submarine was too tall to image the squid in detail, but researchers were able to identify distinct features that identify it, such as the squid’s very large dorsal fin and unique swimming posture. The tentacles of the squid were relatively short, so researchers hypothesized that the deep-dwelling cephalopods were juveniles.
The team published the findings in the journal on December 2, 2021. Marine biology..
