ABSTRACT: The carbon isotope composition (6l3C%0) of the tissues of benthic invertebrates usually ranges from - 16 to -20. In contrast we report that several common bivalve molluscs belonging to the superfamily Lucinacea and several small species of Pogonophora show much greater depletions, ranging from -23 to -31 in the bivalves and from -35 to -46 in the pogonophores. These bivalves and pogonophores live in reducing sediments where the concentration of dissolved sulphide is low, usually < 1 PM. The gills of the bivalves and the trophosome tissue of the pogonophores contain intracellular or sub-cuticular bacteria. The bacteria are autotrophs, as shown by ribulosebisphosphate carboxylase activity of extracts of the bacteria-containing tissues.... |
