Deep-sea mussels living on the "shore" of the Brine Pool. These mussels use methane as their primary source of food, but also filter small particles from the water. The red worms in the bottom left corner are a newly described species of polychaete. The large fish in the middle of the picture is a deep-sea eel. Such fishes commonly visit the Brine Pool, where there is more abundant food than elsewhere on the deep-sea floor. Image courtesy of Gulf of Mexico 2002, NOAA/OER.
