Molecular phylogenetics and the evolutionary history of reproductive strategies in benthic shallow-water octopuses (Cephalopoda: Octopodinae)
… as they are only one of two groups within the Cephalopoda that maintain such a dichotomy. The reconstructed pattern of evolution in inferred juvenile types showed that the planktonic juvenile type was ancestral among 22 species and three independent evolutionary transitions to the benthic …

Molecular phylogenetics of the Metazoan clade Lophotrochozoa
… a close relationship between the Scaphopoda and Cephalopoda. Phylogenetic trees with this topology were found to have likelihood scores significantly better than those for phylogenies constrained to fit the Diasoma hypothesis grouping Scaphopoda and Bivalvia as sister taxa. Chapter 3 utilizes LSU …

MICROMORPHOLOGY AND GENE EXPRESSION IN MUSCLE AND SHELL DEVELOPMENT OF THE MOLLUSCA
… clade comprising the Scaphopoda and Gastropoda + Cephalopoda. This is strengthened by expression data of the homeobox gene engrailed, which plays a significant role in molluscan shell formation. While two dorso-lateral centers of engrailed expression, which correspond to the two centers of initial …
