A research team has recorded on video the fish observed at the greatest depth. The event occurred in the Izu-Ogasawara Trench, where a species of the genus Pseudoliparis was filmed at 8,336 meters. This specific finding marks a benchmark for understanding life under conditions of extreme hydrostatic pressure, showing the known limits of fish fauna.
The technology that made filming in the trench possible 🤿
The recording was achieved with unmanned submersible vehicles equipped with high-resolution cameras and pressure-resistant lighting systems. These landers descend autonomously, remain on the bottom to capture images, and then release ballast to ascend. The design of their housings is crucial, as they must withstand pressure equivalent to placing 800 elephants on a small car without deforming.

While we complain about work pressure, this snailfish lives where the weight of the water would crush a conventional submarine. It lives in total darkness, without views and with a menu limited to what falls from above. Its social life must be quiet; at those depths, you easily avoid pesky neighbors. A true example of extreme minimalism and that, somewhere, there's always someone living in harsher conditions.
