Tubeworms, and the seafloor hydrothermal vents where many of them live, were first discovered in 1977 by scientists diving in the Pacific Ocean in the submersible Alvin. Encased in long, hard, white tubes, vent tubeworms absorb chemical-rich fluids emanating from the vents. Inside their bodies, the worms harbor endosymbiotic microbes; in exchange for a safe place to live, the microbes use the vent chemicals to produce organic carbon that feeds the tubeworms. Since 1977, scientists have found many other vent sites in oceans around the world, surrounded by tubeworms, shrimp, clams, mussels, and other deep-sea life sustained in the absence of light and photosynthesis by vent fluids. But curiously, they had never found a tubeworm at a hydrothermal vent in the Atlantic Ocean. Until this guy, which was discovered during a 2011 expedition to the Mid-Cayman Spreading Center. See story on Page 26.
