  1. MICROMORPHOLOGY AND GENE EXPRESSION IN MUSCLE AND SHELL DEVELOPMENT OF THE MOLLUSCA

    … the molluscan classes Polyplacophora, Bivalvia, Scaphopoda, and Gastropoda. Special reference is given to the shell musculature. In addition, aspects of the myo-anatomy of adult Solenogastres are reconsidered. A further part of this study deals with scaphopod shell morphogenesis and expression of …

  3. Comparative neuroanatomy of Mollusks and Nemerteans in the context of deep metazoan phylogeny

    … Caudofoveata, Solenogastres, Polyplacophora, and Scaphopoda. By comparing the neuroanatomy of those different taxa it is demonstrated that the presence of two pairs of nerve cords of the medullary type is the main unifying feature of the three non-conchiferan taxa. In other respects, the great …
