Scientists have filmed a fish swimming at an extraordinary depth in the ocean, making it the deepest observation of this nature that has ever been made. The species – a type of snailfish of the genus Pseudoliparis – was filmed swimming at 8,336 meters (27,349 feet). It was filmed by an autonomous “lander” dropped into the Izu-Ogasawara Trench, south of Japan.
