摘要：

The discovery of hydrothermal vents and the unique, often endemicfauna that inhabit them represents one of the most extraordinaryscientific discoveries of the latter twentieth century. Not surprisingly,after just 30 years of study of these remarkable—and extremelyremote—systems, advances in understanding the animals and microbialcommunities living around hydrothermal vents seem tooccur with every fresh expedition to the seafloor. On average, twonew species are described each month—a rate of discovery that hasbeen sustained over the past 25–30 years. Furthermore, the physical, geological, andgeochemical features of each part of the ridge system and its associatedhydrothermal-vent structures appear to dictate which novelbiological species can live where. Only 10 percent of the ridgesystem has been explored for hydrothermal activity to date (Bakerand German, 2004), yet we find different diversity patterns in thatsmall fraction. While it is well known that species composition variesalong discrete segments of the global ridge system, this "biogeographicpuzzle" has more pieces missing than pieces in place.
