Abstract / Introduction / Summary:
The microbenthic fauna was investigated in the Okazen tidal flats of Tokunoshima Island and compared with that in the Tekebu tidal flats of Amami- Oshima Island. A total of 32 species, including 24 crustacean species, were sampled in the Okazen tidal flats, while 76 species, including 23 crustacean and 27 gastropod species, were sampled in the Tekebu tidal flats. The species diversity of gastropods and bivalves in the Okazen tidal flats was much lower than in the Tekebu tidal flats. Benthic animal density was also lower in the former than the latter.
