Worms in Sulphur Cave, Steamboat Springs, Colorado. These worms are believed to live on the chemical energy in the sulfur in the cave, similar to the way tube worms live in a world without light at the bottom of the ocean. Also visible on the left side of the image are streamers — colonies of microorganism, similar to those seen in hot springs in Yellowstone National Park. Norman R. Thompson hide caption
