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;
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).

The entrance zone is where the surface and underground environments meet. Light becomes scarcer in the twilight zone. The transition zone is almost completely dark; however some outside environmental effects can still be felt. Finally, the deep cave zone is completely dark, relatively stable, and exhibits no evaporation.
A deep-diving robot that chiseled into the rocky Pacific seabed at a spot where two of the immense plates comprising Earth's outer shell meet has unearthed a previously unknown realm of animal ...
Other trogloxenic animals include vertebrates such as bears, hyenas, other predators, reptiles, oilbirds, cave swiftlets and even humans, that enter for short term shelter or for hibernation. Most of them contribute organic matter rather than consuming it, and are important resources for troglobitic insects, many of which actually specialise in ...
Stygofauna can live within freshwater aquifers and within the pore spaces of limestone, calcrete or laterite, whilst larger animals can be found in cave waters and wells. Stygofaunal animals, like troglofauna, are divided into three groups based on their life history - stygophiles, stygoxenes, and stygobites.
Pygmy rabbits are normally found in areas on deep soils with tall, dense sagebrush which they use for shelter and food. [22] [23] [24] Individual sagebrush plants in areas inhabited by pygmy rabbits are often 6 feet (1.8 m) or more in height. [24] Extensive, well-used runways interlace the sage thickets and provide travel and escape routes. [22]
The town is referred to as the "opal capital of the world." Coober Pedy is an Aboriginal word that roughly translates to "white man in a hole." The town's summer months can reach 120 degrees ...
