| Research Abstract |
Molecular phylogenetic trees were reconstructed for six gastropod lineages to reveal the evolutionary relationships among various chemosynthetically nourished deep-sea habitats, including the hydrothermal vent, cold seep and whale carcass as well as other biogenic substrates. Each study clade(Phenacolepadidae, Neomphaloidea, Lepetelloidea, Seguenzioidea, Abyssochrysoidea and Orbitestellidae s. l.) apparently has diverged through frequent and complex habitat shifts, suggesting that vents and seeps are less specialized ecosystems than previously thought.
