1. Food chains in the ocean are long and complex

2. Hydrothermal Vents
Form from volcanic activity

3. Deep Ocean technology has advanced throughout the years
Deep Ocean technology has advanced throughout the years. Today, we mostly us ROVs (remotely operated vehicles)

4. Before 1977, we believed life could not exist on the bottom of the ocean
Organisms that live here can endure extreme temperatures, pressures, and toxic chemicals

5. Hydrothermal Vent Life
Instead of photosynthesis, organisms have evolved using chemosynthesis (instead of using sunlight for energy, they use acidic gases released from the hydrothermal vents)
