深海热液喷口：无光世界里的奇特生命
Far beneath the ocean surface, along the dark ridges of Earth’s tectonic plates, a strange kind of oasis exists. These are hydrothermal vents — cracks in the seafloor where superheated, mineral-rich water erupts like underwater geysers. At temperatures that would melt lead, no sunlight penetrates, yet life not only survives but flourishes.
The key to this miracle is chemosynthesis. Instead of relying on photosynthesis, bacteria and archaea here convert chemicals like hydrogen sulfide into energy. These tiny extremophiles form the base of a food web that includes giant tube worms, blind shrimp, and strange fish. Their existence challenges our very definition of what a habitable world looks like.
