Departmental Bulletin Paper

In our previous paper, we reported that the archaeogastropod snails living in an intertidal rocky shore could be collected easily and were good teaching materials for observing living spermatozoa. In this study, living spermatozoa were observed in 19 species of 12 families of the mesogastropod and neogastropod snails living in the Pacific coast of the central and southern Japan. Atypical spermatozoa were found in 11 species of nine families. Morphological characters of these spermatozoa were described, and functions of atypical spermatozoa in some species were discussed.
