Chemoautotrophic symbiotic relationships
These relationships are similar to the symbiosis between shallow-water reef corals and their photosynthesizing algae. Like some species of corals, which must be exposed to sunlight to reap the benefits of their
algal partners, vent animals must live exposed to hydrothermal vent fluids in order to benefit from their bacterial symbionts.
