Eriocheir japonica
Taxonomic Group: Crustaceans-Crabs


Eriocheir japonica, the Japanese Mitten Crab, is native to estuaries, rivers, and lakes of southern Russia, Japan, southern China, Hong Kong, the west coast of Taiwan, and southeastern Korea. Like the better known E. sinensis (Chinese Mitten Crab), E. japonica is catadromous, growing to adulthood in freshwater rivers and lakes, and migrating downstream to estuaries for spawning. Only one specimen of E. japonica has been reported from beyond its native range. It was found at the mouth of the Columbia River in Oregon and no subsequent individuals were reported.
