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). [1]
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 ...
One point of contention in the discussion of troglomorphism, is the ultimate evolutionary implications to adaptation to life in caves. Scientists have debated if adaptation to cave life will ultimately lead to evolutionary stagnation, or a point at which evolutionary change becomes minimal.
The overall climates of these caves do not significantly change throughout the year. Humidity in such caves is generally high ranging from 95 to 100 percent; evaporation rates are low. The cave ecosystem in which troglofauna reside can be divided into four zones: entrance, twilight, transition and deep cave. [4]
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.
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.

Stygofauna are any fauna that live in groundwater systems or aquifers, such as caves, fissures and vugs. Stygofauna and troglofauna are the two types of subterranean fauna (based on life-history). Both are associated with subterranean environments – stygofauna are associated with water, and troglofauna with caves and spaces above the water table.
