The Ocean and Sea around Japan is home to some of the deepest trenches anywhere in the world. Despite covering approximately 70% of our planet, only 5% of the ocean is thought to have been explored and mapped.
This has meant that a recent discovery by the Japan Agency for Marine-Earth Science and Technology is even more fascinating. The agency broadcast with the help of NHK the images of a fish at a record 8,178 meters (26,830 ft.) depth.
The fish, which is believed by marine biologist to be a Mariana snailfish, can be seen in the footage approaching beach fleas that have been baited using pieces of mackerel. Whilst it is not known how deep this fish can survive owing to the extreme pressures at this depth, it is the deepest this fish has been observed. The footage was taken at the Mariana Trench, the deepest of all oceanic trenches at 11,034 meters (36,201 ft.).
This bizarre new species of snailfish is now thought to be the deepest known fish. The discovery of one so deep begs the question; how many more things are we yet to discover in our oceans?
