New species discovered in ocean's hadal zone

Researchers have discovered over 7,500 microbial species in the hadal zone, with 89% being previously unknown. This area, located 19,700 to 36,000 feet below sea level, is one of Earth's least explored regions. Using a Chinese submersible, scientists collected samples from the Yap Trench, Philippine Basin, and Mariana Trench. Their findings reveal surprising diversity and adaptive strategies among microorganisms and larger creatures in extreme conditions. The studies also found human litter, including plastic and cans, at these depths. This highlights the impact of human activity even in the most remote ocean environments.
