| Abstract |
The Ogasawara (Bonin) Islands are an oceanic island group and World Natural Heritage site in Japan. This study reports the first record of the freshwater prawn Macrobrachium australe (Guérin-Méneville, 1838) on Chichi Island in the Ogasawara Islands. Although this amphidromous species has high dispersal ability, our comprehensive surveys across the islands found only one individual, with no evidence of establishment or reproduction. This case study of the accidental dispersal of amphidromous species to oceanic islands is significant from a biogeographical perspective. |
