Abstract

The shell structure of three deep-sea vesicomyid clams (i.e., Calyptogena magnifica, Calyptogena phaseoliformis, and Calyptogena c.f. pacifica) is characterized by scanning electron microscopy (SEM). SEM examination of shell fracture sections of these vesicomyids reveals a variety of shell microstructures in distinct arrangements. The shell of Calyptogena magnifica consists of layers of planar spherulitic, fine complex crossed lamellar, cone complex crossed lamellar, and irregular simple prismatic structure, and that of Calyptogena phaseoliformis is comprised of layers of fine grained homogeneous, planar spherulitic, fine complex crossed lamellar, irregular spherulitic prismatic, and irregular simple prismatic structure. In Calyptogena c.f. pacifica, the shell contains layers of planar spherulitic, fine complex crossed lamellar, vertical non-denticular composite prismatic, and irregular simple prismatic structure. While cone complex crossed lamellar structure is only observed in Calyptogena magnifica, fine grained homogeneous and irregular spherulitic prismatic structures only occur in Calyptogena phaseoliformis. Vertical non-denticular composite prismatic structure is found exclusively in Calyptogena c.f. pacifica.
