Tongue fish and crabs are part of the extensive vent community on the sea floor at Daikoku. The fish blend in well on this pebbly substrate, but it is easy to spot the larger fish (in the bottom right corner of this image). The lasers — two red dots in the center of the image — are 10 cm (4 in) apart. Image courtesy of Submarine Ring of Fire 2006 Exploration, NOAA Vents Program
