Encyclopedia > Troglobite

A troglobite is an animal that lives entirely in the dark parts of caves. Such creatures have become specifically adapted for life in total darkness and over time they have evolved to develop improved senses of smell, taste and vibration detection, while losing anatomical features that are superfluous without light, such as functioning eyes and pigmentation. Specific examples include the Texas cave salamander, the blind cave fish and cave crickets; there are numerous fish, shrimp, crayfish, eyeless flatworm, pseudoscorpions, spiders, millipedes, and other insects with this property. Troglobites are often endemic to a certain site, having adapted to its particular environment and food sources. True troglobites are eyeless. Troglophiles have some sight.

An aquatic troglobite is sometimes called a stygobite.[1] Stygobites are synonymous with stygofauna. Stygofauna are any fauna that live within groundwater systems, such as caves and aquifers, or more specifically small, aquatic groundwater invertebrates, though terrestrial air-breathing subterranean animals are also sometimes included. ...


In addition, the term troglobite is often used as an insult, meant to indicate someone who is blind to their surroundings, either intentionally or through general lack of intelligence.

Cave - Wikipedia, the free encyclopedia (1476 words)
Cave inhabiting animals can be categorized as troglobites (cave limited-species), troglophiles (species which can live their entire lives in caves, but also occur in other environments), trogloxenes (species which utilize caves, but must leave the caves to complete their life cycle) and accidentals.
Troglobitic species often show a suite of characters, termed troglomorphies, associated with their adaptation to subterranean life.
Aquatic troglobites (or stygobites), such as the endangered Alabama cave shrimp, live in bodies of water found in the caves and are fed by detritus washed into the caves, and by the feces of bats and other cave inhabitants.
Biospeleology (1148 words)
Troglobites have great senses of smell and touch allowing a more efficient life for cave dwelling animals.
An interesting aspect of Troglobite’s lives are the possibility that species of such could have survived in the caves as other species above ground became extinct.
Evidence of Troglobite species that once lived in the cave and had been well preserved in the stable cave environment (Figure 5).
