| Outline of Final Research Achievements |
More than 20 animal phyla are known from minute environment between sand particles in beaches. A number of interstitial species are known in the phylum Annelida, a group that is mainly comprised of lugworms, earthworms, and leaches. At the onset of this study, 11 species in eight genera of interstitial annelids had been reported from Japanese waters. No representative of the genus Diurodrilus had been known in Japan, but there is an undescribed form in Ishikari Beach, Hokkaido. This study aimed to test the phylum affiliation of such interstitial annelids as Diurodrilus and Trilobodrilus, which was doubted by previous studies. The conclusion, however, was that both groups actually belong to the phylum Annelida.
