Neomysis japonica
Taxonomic Group: Crustaceans-Mysids


Neomysis japonica is a Mysid crustacean native to the Northwest Pacific, from central Japan to the South China Sea. Mysids are small, shrimplike crustaceans, which tend to divide their time between epibenthic habitats and the plankton. It has been introduced to San Francisco Bay, California and New South Wales, Australia. The abundance and distribution of N. japonica in San Francisco Bay is poorly known because of taxonomic confusion with N. kadakiensis. It is found in estuaries and lagoons and has been recorded within ballast water from commercial ships.
