||Areas dominated by chemoautotrophic bacteria living on or near hydrothermal vents.
These bacteria can use the chemicals present around the vent as an energy source.
The bacteria are present in the water column and on substrate near vents as bacterial
mats, films, and strands. They form the primary food source (as symbionts or as free-living
bacterial clusters) for the gigantic and diverse fauna that inhabit Vent Communities.
Vent Microbes colonize new vents, making the area hospitable to other fauna.
