Checklist of the micromolluscs in the intertidal zone of the Yellow Sea and Bohai Sea, China

The diversity of the sedimentary environment and molluscs is rich in the intertidal zone of the Yellow Sea and Bohai Sea. At present, many of the investigations focus on macromolluscs, while the diversity of micromolluscs is seriously underestimated. New information In this study, the survey of micromolluscs was carried out in the intertidal zone of the Yellow Sea and Bohai Sea. The collection and preservation of micromolluscs, as well as the preparation methods of morphological characteristic structures by scanning electron microscopy (SEM) were explored. A total of 20 species were described in this survey. These can be assigned to 16 families, four orders (Vetigastropoda (1), Caenogastropoda (10), Heterobranchia (5) and Autobranchia (3)) and two classes (Gastropoda (17), Bivalvia (3)).
