Depressed river mussel

Depressed River Mussel Pseudanodonta complanata

The Depressed River Mussel is a rare, green or brown river bivalve. The shell is wedge shaped, with the umbo (the rounded knob) positioned to one side. It gets its name from its compressed appearance; it looks like someone has squeezed the two shells together. Image: Tom Meijer (iNaturalist).
