At a depth of 8.336 meters in Japan, cameras captured a white, ghostly fish that set a world record — and next to it appeared a creature that science has never seen.

Pseudoliparis snailfish filmed in the Izu-Ogasawara Trench breaks previous record by 158 meters — cameras also captured a white, ghostly organism that defies biological classification

High-resolution cameras dove to a depth of 9,100 meters in the ocean trenches of Japan. What they recorded surprised even the most experienced scientists.

At 8,336 meters, the equipment filmed a Pseudoliparis snailfish swimming and feeding normally.

This is the new world record for observing a living fish. The previous record was 8,178 meters in the Mariana Trench.

How the record was broken

The scientific team focused on the Izu-Ogasawara and Ryukyu trenches, south of Japan.

Autonomous cameras were sent to 9,100 meters. They withstand pressures of over 900 atmospheres.

The snailfish appeared at 8,336 meters. It was filmed in action — swimming and searching for food in the sediment.

The species belongs to the genus Pseudoliparis, of the family Liparidae. They are small, gelatinous, and translucent fish.

They do not have a swim bladder. The extreme pressure prevents this organ from functioning in the depths.

Their bodies are predominantly water. This makes them flexible enough to withstand absurd pressures.

The ghostly creature no one expected

Alongside the snailfish, the cameras recorded a white organism with a singular morphology, never before documented.

Scientists provisionally classified it as Animalia incerta sedis. In Latin, it means “animal of uncertain classification”.

The creature does not fit into any known zoological group. Its appearance is ghostly — white, gelatinous, and shapeless.

It could be a new species, a new genus, or even an entirely new family. Genetic analysis has yet to be conducted.

Discoveries like this show that the ocean floor holds more secrets than the surface of the Moon.

The numbers of the abyss

Depth of the fish: 8,336 meters
Previous record: 8,178 meters (Mariana Trench)
Difference: 158 meters
Cameras sent to: 9,100 meters
Pressure at this depth: over 900 atmospheres
Location: Izu-Ogasawara Trench, Japan

At 900 atmospheres, a human would be crushed instantly. Snailfish have evolved to thrive there.

Impressive record, but the deep ocean holds limitations

The record is visual, made by camera. No physical sample of the fish or the unknown creature was collected.

The classification of the creature as incerta sedis means it may take years before it is formally described.

The abyssal depths are the least explored environment on the planet. Each dive reveals never-before-seen species.
