Grotto Sculpin (Cottus specus)
The grotto sculpin is a small fish found mostly in cave streams. Its entire range is within Perry County, Missouri, in an area with thousands of sinkholes and over 700 caves (collectively called a “karst system”). The U.S. Fish and Wildlife Service has listed the grotto sculpin as endangered. Contamination of cave streams where the grotto sculpin lives is the primary reason that this fish could become extinct.
