Marine biologists exploring the Mariana Trench have identified three previously unknown species living at depths exceeding 8,000 meters.
The creatures, discovered during a month-long expedition using advanced remotely operated vehicles, include a translucent fish with bioluminescent organs, a new type of amphipod, and a colonial organism unlike anything previously documented.
"Finding not one but three new species at these extreme depths tells us how much we still have to learn about our own planet," said the expedition leader.
The discoveries are particularly significant because the organisms appear to thrive in conditions of crushing pressure and near-freezing temperatures, offering new insights into the limits of life on Earth and potentially on other worlds.
