"This species is native in the Gulf of Mexico, and spread from there via ballast water, or attached to oysters that were moved, to the Hudson River in the 1930s, and from there to other estuaries in the eastern US including Chesapeake Bay... Like the zebra mussel, this species is a significant biofouling pest in many countries, especially where it has been introduced in Europe" (Wikipedia, accessed 10/16/2017).
