Japanese researchers have succeeded in taking a video on the ocean floor of a deep-sea bony fish that is over 2.5 meters in length. Named the "yokozuna slickhead," the creature is known as the largest bony fish species in the world among deep-sea fish that live in waters deeper than 2 kilometers, except for cartilage fish such as sharks and rays.

So far, six yokozuna slickhead fish have been caught in a deep-sea area in Suruga Bay of Shizuoka Prefecture in central Japan, with the largest one measuring 1.38 meters long. The fish was reported as a new species in 2021. The Japan Agency for Marine-Earth Science and Technology (JAMSTEC) was surveying the large deep-sea fish, and took the video on the ocean floor south of the bay.
