Flexing Delaware's Mussels
North America is home to over 300 species of freshwater mussels, but 75 percent of them are endangered.
Not too many people know about the freshwater bivalve, said Danielle Kreeger, science director at the Partnership for the Delaware Estuary, a clean water nonprofit. It’s considered the most “imperiled” of all plants and animals in North America.
“Here in the Delaware River Basin, in the state of Delaware, there’s about a dozen native species and really you can only find two or three of those,” Kreeger said.
