Good morning, I'm A Martínez. Scientists have film of a snailfish swimming in a trench south of Japan at more than 27,000 feet down - the deepest ever recorded. They say that's very close to the maximum depth a fish could survive at. And if this record is ever broken, it would only be by a few feet at the most.
