Kingdom Phylum Class Order Family
ANIMALIA MOLLUSCA BIVALVIA UNIONOIDA UNIONIDAE

Scientific Name: Elliptio complanata
Species Authority: (Lightfoot, 1786)
Common Name(s):
English Eastern Elliptio
Taxonomic Notes: The classification of the Atlantic Slope species of Elliptio is currently in a state of confusion. Johnson (1970) lumped many named taxa under a single name. Current research is finding many of these synonomized taxa to be valid species. This research is in progress and will result in the recognition of numerous additional taxa in this genus.

A list of synonyms for this species can be found on The MUSSEL project web site (Graf and Cummings 2011).
