Notes"Assiminea parasitologica is a small intertidal estuarine mesogastropod snail native to Japan. This species was first documented in the Coos Bay Estuary, Oregon in June of 2007." Because the new species might create problems for native snails, a study was started in 2008. Baseline data was gathered on the new species, native gastropods Angustassiminea californica and Littorina subrotundata and another invasive snail, Myosotella myosotis. "The primary goal of the study was to obtain a current (2009) snap shot of the status of Assiminea parasitologica in Pacific Northwest Estuaries." (from the Executive Summary) Colored maps show where the invader was found. Along with the final report is an interactive .pdf map showing the distribution of A. parasitologica in Coos Bay.
