Non-native Corbicula (Asian clam) bivalves have become established in many states across the United States. While these invasive organisms are prevalent in many areas, little is known about the distribution of the genetically and morphometrically distinct forms within the Corbicula genus. Although Corbicula have been found throughout Florida, we recorded the first known observation of Form D Corbicula in both Florida and the Atlantic watershed. Distribution information on Corbicula forms is important information for managers attempting to understand and control these invasive bivalve populations.
