A grove of unidentified sea fans with resident brittle stars (Asteroschema sp.) coiled in their branches near the crest of a lithoherm at 580 to 600 m (1,903 to 1,969 ft) depth. The white colony (center rear) is the branching stony coral Lophelia pertusa. The golden fan (right rear) is the colonial anemone Gerardia sp., with a white chyrostylid squat lobster clinging to it. © A. Conrad Neumann. Image courtesy of Bioluminescence Team 2009, NOAA-OER.
