The deep sea, covering approximately 65% of Earth's surface, has long been considered a biological desert. In this extreme environment—particularly in the hadal zone at depths greater than 6,000 ...

The hadal zone, which extends from 6 to 11km (20,000 to 36,000ft), is a forbidding place, characterised by complete darkness, crushing pressure and near-freezing temperatures.

Earth’s hadal zone includes marine regions 19,700 to 36,000 feet (6,000 to 11,000 meters) below sea level. The reference to the Greek god of the underworld, Hades, is not coincidental—these ...

We don’t yet know how much deeper fish might live in the hadal zone. Recent expeditions such as the HADES project in the Pacific suggest that fish are not found below 27,560 feet.

In a new study, published March 6 in the journal Cell, researchers analyzed the DNA of 11 fishes, including snailfish, cusk-eels and lizardfish that live in the hadal zone — the region about ...
