This Astrobiology Magazine article reports that a research team of marine scientists has determined that water chemistry controls the location and distribution of two species of weird worms inhabiting deep-sea hydrothermal vent sites: the tubeworm (Riftia pachyptila) and Pompeii worm (Alvinella pompejana). The article includes color images of the worms and monitoring equipment, links to related web pages and other astrobiology resources, and an MP3 machine text-to-speech function.
