Tongue fish and crabs are part of the extensive vent community on the seafloor 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 - 2 red dots in the center of the image - are 10 centimeters (4 inches) apart. Image courtesy of Submarine Ring of Fire 2006 Exploration, NOAA Vents Program
