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).

Tooth Cave pseudoscorpions fall under the category of troglobites, which are species that spend their entire lives in caves. Some distinct features of troglobites include attenuated palps and long, slender appendages. [5] Tooth Cave pseudoscorpions are large for cave-dwelling species in this area, measuring about 4 mm (0.15 in) in length.
Caves tend to be geologically short-lived, so most of the specialised adaptations are correspondingly young in evolutionary terms and to have arisen rapidly and in parallel from similar ancestors that began as similar troglophiles in separated caves. Many insect troglobites are Orthopteran, Collembolan, or Blattodean, for example, and given the ...
The land was put up for sale in 1940. Local officials worked with the U.S. Forest Service to purchase the land and keep it from an interested timber company. ... There are about 30 caves on the ...
This would suggest that caves are highly influential in the persistence of species, and the preservation of biodiversity. [ 10 ] [ 11 ] In fact, many of these lineages show similar rates of speciation and diversity even within these smaller habitats, as uniquely specialized colonists of another environmental niche, rather than an evolutionary trap.
The microscopic cave snail Zospeum tholussum, found at depths of 743 to 1,392 m (2,438 to 4,567 ft) in the Lukina Jama–Trojama cave system of Croatia, is completely blind with a translucent shell. Troglofauna are small cave-dwelling animals that have adapted to their dark surroundings.
Troglobites are obligatory cavernicoles, specialized for cave life. Some can leave caves for short periods, and may complete parts of their life cycles above ground, but cannot live their entire lives outside of a cave environment. Examples include chemotrophic bacteria, some species of flatworms, springtails, and cavefish.
Caves that are close to the surface, such as lava tubes, often have tree roots hanging from the cave roof, which provide nutrients for sap-feeding insects. [ 1 ] [ 2 ] Other important food sources in underground habitats are animals being decomposed and bat guano , [ 3 ] [ 4 ] [ 5 ] that creates large invertebrate communities in such caves.
