What is the Mariana Trench marine ecoregion?

The Mariana Trench is the deepest place on Earth, nearly 11,000 meters down. It is dark, cold, and under crushing pressure. Only hardy animals like snailfish and amphipods, shrimp-like creatures, can live here. Life depends on “marine snow,” a slow rain of dead plants and animals.
