Abstract

Results indicate a growth rate of 14 cm/yr for the large Riftia tube worm, of 9.2 cm/yr for the small Tevnia tube worm and up to 9.5 mm/yr for the mussel Bathymodiolus. The corrosion rate of the aragonite shell of Calyptogena (large white clam) was as great as 0.25 mm/yr in 3°C vent water, and 0.026 mm/yr in 1.8-2°C abyssal water. Microbial activity appears to play an important role in shell dissolution, with rates dependent on shell layer microstructural type. The small pectinid Bathypecten vulcani has a larval shell indicative of a lecithotrophic mode of development. There is an abridged English version. -from English summary
