The Amblyopsidae are a fish family commonly referred to as cavefish, blindfish, or swampfish.They are small freshwater fish found in the dark environments of caves (underground lakes, pools, rivers and streams), springs and swamps in the eastern half of the United States.
A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors (subtroglophiles and trogloxenes).

Cave salamanders are found in Europe and the U.S., but only some of these (such as the olm and Texas blind salamander) are entirely aquatic. The approximately 170 species of stygobite fish, popularly known as cavefish, are found in all continents, except Antarctica, but with major geographical differences in the species richness. [6] [7]
The status and distribution of cave-obligate species is incomplete or lacking entirely, which makes conservation and management decisions difficult. [8] This species is listed as endangered in Missouri. The IUCN Red List considers the spring cavefish to be of least concern due to its relatively large population size and number of subpopulations.
The northern cavefish was under consideration for listing under the Endangered Species Act, however, the U.S. Fish and Wildlife Service found in 2023 that despite the loss of two metapopulations of A. spelaea, listing was not warranted, as the four metapopulations that still exist had sufficient redundancy of subpopulations to mitigate threats.

Key Cave is the critical habitat of the Alabama cavefish. [12] Cave habitats tend to be stable, with drastic changes mainly being associated with the inflow of water. [13] Annual rainfall and flooding in the cave produce changes in water level, temperature, and food availability for the fish. [13]
