Rhizophora mucronata, Avicennia marina, Lunmitzrea racemosa
and Sonneratia alba, the forest of which is collectively
designated as a National Natural Monument. Rare distribution site
of mangrove tree species. Geographically rare distribution site
of mangrove forests. Representative and endemic distribution site

ecosystems. |
Freshwater
fish |
Rivers in
Iriomote-jima |
Rich in species diversity of subtropical freshwater
fish, such as Crenimugil heterocheios. Toxotes jaculator
and Lutjanus goldiei are found in Urauchi-gawa (river), and
Rhyacichthys aspro in the upper reaches of Omija-gawa and
Nakama-gawa. |
| Crustaceans |
Mangrove forests and estuary of Nakama-gawa |
As Nakama-gawa and its tributaries support 3 rare
species listed in the RDB (Neocaridina brevirostris, Macrobrachium
shokitai and Geothelphusa minei), the entire river basin
is important. In recent years, a possibly new Neocaridina sp. has
been discovered in a tributary of Nakama-gawa. |
| Benthos |
Estuaries of Nakama-gawa, Shiira-gawa and Maira-gawa |
These areas encompass some of the largest mangrove wetlands in Japan. They have a rich species diversity in benthos, specific to mangrove wetlands. |
