Urauchi-irie
(Estuary of
Urauchi-gawa) |
Habitat of Kandelia candel, Bruguiera gymnorhiza,
Rhizophora mucronata, Avicennia marina and Lunmitzrea racemosa.
Rare distribution site of mangrove tree species. Geographically
rare distribution site of mangrove forests. Representative and endemic
distribution site of mangrove forest ecosystems. High diversity
of mangrove forest ecosystems. |
Freshwater
fish |
Rivers in
Iriomote-jima |
These rivers have a high 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. |

Mangrove
forests and
estuary of
Urauchi-gawa |
As the brackish zone of Urauchi-gawa supports many
peripheral freshwater fish and crustaceans, and freshwater zone
supports rare or vulnerable crustaceans and gobies, the entire river
basin is important. The mangrove channels are inhabited by valuable
tropical species such as Toxotes jaculator and Lutjanus
goldiei, and upstream area supports valuable landlocked species
such as Macrobrachium shokitai, Neocaridina brevirostris
and Geothelphusa minei. |
| Benthos |
Estuary of
Urauchi-gawa |
This estuary is rich in benthos specific to mangrove wetlands.
It is the sole place in Japan where Macrophthalmus (Venitus)
latreillei is observed in the intertidal zone. |
