Scientists film deepest ever fish on seabed off Japan

CNN — Cruising at a depth of 8,336 meters (over 27,000 feet) just above the seabed, a young snailfish has become the deepest fish ever filmed by scientists during a probe into the abyss of the northern Pacific Ocean.

Scientists from University of Western Australia and Tokyo University of Marine Science and Technology released footage of the snailfish on Sunday filmed last September by sea robots in deep trenches off Japan.

Along with the filming the deepest snailfish, the scientists physically caught two other specimens at 8,022 meters and set another record for the deepest catch.

Previously, the deepest snailfish ever spotted was at 7,703 meters in 2008, while scientists had never been able to collect fish from anywhere below 8,000 meters.

“What is significant is that it shows how far a particular type of fish will descend in the ocean,” said marine biologist Alan Jamieson, founder of the Minderoo-UWA Deep Sea Research Centre, who led the expedition. ..............(more)

1. How do they handle the incredible pressure at that depth? Amazing

2. Hard to imagine.

4. Same internal pressure as outside

3. Looks like an anime fish.

5. What, like 12,000 psi at that depth?

I guess if the pressure on the inside of the fish is equal to the pressure on the outside, it makes little difference.
