Nagura Amparu is a brackish estuary system with a tidal flat and mangrove tree area separated from the outer sea bay by a sandbank. Land hermit crabs were captured using bait traps at three sites along the shoreline of the sandbank facing the inner tidal flat and at one site in the coastal forest on the sandbank. Four land hermit crab species, Coenobita brevimanus, C. cavipes, C. rugosus, and C. violascens, were collected. Almost all collected crabs were C. violascens, and a few C. rugosus were collected on the shoreline. On the other hand, C. cavipes was dominant, followed by C. violascens, and a few C. brevimanus were captured in the coastal forest. Coenobita violascens were juveniles and adults, and they widely inhabited the shoreline and coastal forest. All C. cavipes were juveniles, suggesting that this species utilizes the coastal forest as a nursery ground. Our results highlight the importance of the Nagura Amparu as habitat for juveniles and adults of C. violascens and juveniles of C. cavipes.}, pages = {142--149}, title = {Distributions of land hermit crabs (Decapoda: Coenobitidae) on the coast of the tidal lagoon, Nagura Amparu, on Ishigakijima Island, Japan.}, volume = {19}, year = {2017} }
