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 dwelling animals show different levels of adaptations to underground environment. According to a recent classification, animals living in terrestrial subterranean habitats can be classified into 3 categories, based on their ecology: troglobionts (or troglobites): species strongly bound to subterranean habitats;
In contrast to the rarer species, the cave form of the Mexican tetra is easily bred in captivity and widely available to aquarists. [68] [103] This is the most studied cavefish species and likely also the most studied cave organism overall. [104] As of 2006, only six other cavefish species have been bred in captivity, typically by scientists. [56]
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.

The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna, and an important apex predator across its range. It became extinct about 13,000 years ago. [ 4 ]
