How Does Life Survive Beside a 339°C Deep-Sea Vent?

Vent fluid at 339°C. Shrimp and crabs living beside it. How is that possible -and what feeds them when sunlight never arrives? Follow real expedition footage from the Mariana back-arc and Moytirra on the Mid-Atlantic Ridge. In three minutes, we explain the mixing of hot fluid and cold seawater, mineral chimneys, pressure, and the microbes that help support a food web through chemosynthesis. The temperature refers to measured vent fluid at the outlet, not the body temperature of the animals. Diagrams are labelled schematics; the mineral-growth scene is an illustration, not a time-lapse.
