Sagittunio nasutus, Eastern pondmussel
Sagittunio nasutus, the eastern pondmussel, is a species of freshwater mussel in the family Unionidae, the river mussels.
This species is native to the eastern United States and Ontario, Canada. Only two populations are known from Canada. Like many Unionoid mussels, female eastern pondmussels display a lure to attract their fish hosts (see video, right).
