Mammoth Cave National Park 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.
