One of Green River's diverse mussel species

(Kentucky State Nature Preserves Commission)

The Green River in Mammoth Cave National Park contains the most diverse population of freshwater mussels in North America, and one of the most diverse populations in the world. Among the species found in the river are the Ring Pink, Rough Pigtoe, Pistolgrip, Fatmucket, Spectaclecase, Plain Pocketbook, Washboard, Sheepnose, and Snuffbox. Several of the mussel species are federally endangered. A snail (Antroselates spiralis) is found in cave environments.

Did You Know?

Did You Know? Native Americans mined minerals in Mammoth Cave for 2,000 years.

Native Americans of the Early Woodland period gathered minerals from Mammoth Cave between 2,000 and 4,000 years ago ... no one knows why. Objects they left behind – slippers, cane torches, gourds, and mussel shells – remain perfectly preserved in the cave.
