A new species of dicyemid mesozoan is described from Sepiella japonica Sasaki, 1929, collected from the eastern area of Inland Sea, Osaka Bay, and Kii Strait in Japan. Dicyema sepiellae n. sp. is a large species that reaches about 4,000 μm in length. This species lives in folds of the renal appendages. The vermiform stages are characterized as having 24–29 peripheral cells, a conical calotte, and an axial cell that extends to the middle of the metapolar cells, but to the base of propolar cells…

Biology of Dicyemid Mesozoans

Recent phylogenetic studies suggest dicyemids are a member of the Lophotrochozoa, and the shape of the calotte changes from conical to cap-shaped and discoidal in some species, and appears to result from adaptation to the structure of host renal tissues.

Development of the Infusoriform Embryo of Dicyema japonicum (Mesozoa: Dicyemidae).

The cleavage pattern and cell lineage of the infusoriform embryo of the dicyemid mesozoan Dicyema japonicum were studied in fixed material with the aid of a light microscope and the cell lineage appears to be invariant among embryos, apart from the derivation of the lateral cells.

Fourteen new species of dicyemid mesozoans from six Japanese cephalopods, with comments on host specificity

The largest cephalopod host species, namely Octopus dofleini, Octopus hongkongensis, and Sepia esculenta, harbored dicyemid species with the longest or largest vermiform stages, and host specificity appears to be characteristic of dcyemid-cephalopod relationships.

Calotte morphology in the phylum Dicyemida: niche separation and convergence

In the dicyemids, calotte morphology seems to result from adaptation to the structure of host renal tissues and helps to facilitate niche separation of coexisting species.
