[1] It is a species of sea snail most often found in the salt marshes and mudflats of marine, estuarine, riparian and wetland habitats.
[2] Introduced to North America between the 1920s to 1930s via the coasts of Washington and California, the Japanese mud snail became an invasive species notorious for reducing biodiversity by outcompeting the native hornsnail Cerithidea californica.
[4] The native range of Batillaria attramentaria extends from the Kuril Islands and southern Sakhalin, Russia, to Hong Kong.
It has been introduced into North America, where it now occurs from Boundary Bay, British Columbia, Canada, to Elkhorn Slough, Monterey, California, USA.
Due to Batillaria attramentaria's superior abilities to compete for food, habitats in which the species has been introduced typically see a drastic drop in the population of California hornsnails.
