Animal communities, including thousands of tubeworms and bivalves, have been observed at depths up to 9,533 meters in the Mariana Trench, marking the deepest and most extensive chemosynthesis-based ecosystems known. These organisms rely on chemical energy, such as methane produced by microbes, rather than sunlight, indicating that such deep-sea life may be more widespread than previously recognized.
