Eyeless Cave Fish

Perhaps the most unusual fish in Mammoth Cave National Park are those cave-adapted species known generally as eyeless fish. They have adapted to lightless, low-energy environments by ceasing to grow eye structures and unnecessary skin pigments. Surface fish include most game fish found in the eastern United States, including bluegill, crappie, largemouth bass, muskellunge, yellow perch, striped bass, gar, and catfish, among others.

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.
