When was the first hydrothermal vent ecosystem discovered near the Galápagos Rift?
Quick Answer
The first vent ecosystem was discovered in 1977. It was the first clear evidence of a community living entirely from seafloor chemical energy.
The Full Story
In 1977, scientists exploring the Galápagos Rift found an active hydrothermal vent ecosystem on the deep ocean floor. Instead of plants, the food web relied on bacteria that used chemicals from vent fluids to make organic matter. Tube worms, giant clams, and other animals were found clustered around the vents in dense communities. This discovery showed that life can flourish in total darkness and high pressure, reshaping marine biology and astrobiology.
