Recently, Japanese researchers said that they photographed a 2.5-meter-long yokozuna sardine at a depth of more than 2,000 meters in Suruga Bay, Shizuoka Prefecture, making it the largest known deep-sea bony fish in the world.

  The Japan Agency for Marine Research and Development (JAMSTEC) placed a camera at a water depth of 2,091 meters in Suruga Bay to capture this precious image in October 2021, and in the same year listed the deep-sea fish as a new species.

The relevant research results were published in the journal Frontiers in Marine Science on July 1.

Scientists at the agency also caught six of the fish, the largest of which was 1.4 meters long.

  Scientists believe that this fish, which has so far been found only in Suruga Bay, is an "apex predator", usually at the top of the food chain.

Top predators are generally the most affected by the Earth's environment and can disrupt local food chains and cause devastating damage to entire ecosystems, scientists say.

In addition, there may also be other giant unknown deep-sea fish varieties inhabiting the local area, which scientists are studying.
