Zeitschrift für Zellforschung und Mikroskopische Anatomie Aims and scope Submit manuscript

Summary

The ultrastructural appearances of the cell types are described in the pars distalis of common (Pacific) dolphins, Delphinus delphis. Tentative functions are assigned to these cells and discussed in relation to some of the known adaptations of these mammals to a marine environment.
