How Deep-Sea Hydrothermal Vent Fields Create Oases of Chemosynthetic Life

Quick fact

Giant tube worms at hydrothermal vents have no mouth or stomach. They are completely dependent on symbiotic bacteria that live inside them and convert chemicals from the vent fluid into food.

Imagine a lush forest thriving without a single ray of sunlight. Deep in the ocean, such ecosystems exist—not of trees, but of towering worms and towering clams—fueled by chemistry, not photosynthesis.
