New species of marine organisms discovered at a depth of 31,000 feet

• New species of marine organisms have been discovered at depths exceeding 31,000 feet.
• The research confirmed the existence of chemosynthetic ecosystems.
• These communities may be more widespread than previously thought.

In the northwestern Pacific Ocean, in the region of the Kuril-Kamchatka and Aleutian trenches, researchers conducted studies using underwater equipment and discovered new species of marine organisms at depths exceeding 31,000 feet (9.5 km). This finding confirms the existence of large marine organisms in the deepest parts of the ocean, where it was previously believed that life was limited due to extreme conditions such as high pressure, lack of light, and others.

Researchers found tube worms and mollusks that survive by relying on chemosynthesis – a process in which microbes convert methane and sulfur compounds into organic matter, which serves as food for other organisms. This is the deepest known chemosynthetic life, which has ever been discovered, according to Mengran Du, one of the authors of the study.

The research also indicated that these ecosystems could be more widespread than previously thought, as life in such depths may be sustained not only by particles that fall from the upper layers of the ocean but also by methane produced by microbes buried beneath the ocean floor.

The results of the research were published in the journal Nature. The researchers hope that future studies will help understand how these organisms have adapted to survive in extreme conditions.
