Scientists Film the Deepest Fish Ever Recorded
A camera dropped into the Izu-Ogasawara Trench near Japan has filmed a snailfish swimming at a depth of 8,336 metres — the deepest any fish has been seen alive.

The facts
- 1Snailfish are small, jelly-like fish that can survive extreme water pressure.
- 2The record was captured by an autonomous deep-sea camera (no diver went down).
- 3At that depth the pressure is over 800 times what we feel at the surface.
- 4The previous record was 8,178 metres in the Mariana Trench.
- 5Scientists believe even deeper fish may exist but are very hard to spot.
Why it matters
Knowing what lives in the deepest parts of the ocean helps scientists understand how life adapts to extreme environments.
