On the geophysics-imaged mud volcanoes over the northwest Dongsha Waters, a large number of deep-water benthic living organisms, fossils, and authigenic carbonate nodules were photographed by our newly developed portable underwater camera on 250-350 m deep seafloor. The organisms comprise abundant deep-water corals, glass sponge, sea anemone, sea lily, fish, shrimp, lobster and bivalve. The photographs further revealed that active methane leakage and mud volcanic activity in the Dongsha Islands area.
