Marine biologists aboard the research vessel Deep Explorer have discovered an entirely new ecosystem in the Mariana Trench, 10,800 meters below the ocean surface — the deepest living community ever documented.
The ecosystem includes over 30 previously unknown species, including translucent crustaceans, bioluminescent worms, and a species of bacteria that derives energy from minerals in the volcanic rock rather than sunlight or organic matter.
"These organisms have evolved completely independently from every other life form we know," said Dr. James Park, chief marine biologist. "They challenge our fundamental understanding of what conditions are necessary for life to thrive."
