Chinese researchers conducting an expedition in the Red Sea have discovered a deep-sea ecosystem more than 10 kilometers beneath the ocean surface. The team encountered several brine pools likely fed by underwater volcanoes, which support unique microbial life and animal species adapted to extreme conditions. Among the findings are colonies of tubeworms and mollusks that consume bacteria thriving on methane in total darkness, representing the deepest known community of such creatures. This discovery challenges existing biological boundaries and suggests the presence of complex life forms in previously unexplored ocean depths. The expedition included record-breaking drilling efforts aimed at reaching even greater depths, revealing a previously unknown network of marine life in extreme environments.
