World's Deepest Squid Discovered at Staggering Depth Under The Sea

Video evidence of the deepest-swimming squid ever recorded was discovered by a team of researchers who were hunting for the wreck of a lost WWII destroyer ship in the Philippine Sea.

The young bigfin squid, a member of the same family as the previous champ, blew the previous champ's record by swimming about 15,400 feet (4,700 meters) below the floor of the Philippine Trench.

The team wrote in a recent study that they recorded four dumbo octopuses around the same depth.

This is the second time that dumbos have been observed so deep, proving that the previous observations were not a mistake.

The dive showed that multiple types of cephalopods can live in the upper parts of the ocean trenches.

"How do big fin squids live at depths ranging from 3,200 to 19,600 feet ( 1000 to 6000 m)," where atmospheric pressures can be up to 600 times greater than at the ocean's surface, is one of the questions raised by the spotted big fin squids.

A big fin squid was observed more than 16,000 feet underwater. The same species was found swimming thousands of feet deeper in 2021.

The big fin was detected in March 2021, while researchers were looking for the wreck of the US Navy destroyer that sank in 1944 during the Battle of Leyte Gulf.

The researchers filmed their dive to the bottom of the Philippine Trench using the same type of submersible that Victor Vescovo used to descend to the bottom of the Mariana Trench.

The team spotted a big fin squid. The researchers were able to identify the squid's identity because of its large back fins and distinct swimming posture, even though the sub was too high to image them.

The researchers thought the squid was a juvenile because of its short tentacles.

The findings were published in the journal Marine Biology.
