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 ...
The terms troglobitic, stygobitic, stygofauna, troglofauna, and hypogean or hypogeic, are often used for cave-dwelling organisms. [1] Troglomorphism occurs in molluscs, velvet worms, arthropods, fish, amphibians (notably cave salamanders) and reptiles. To date no mammals or birds have been found to live exclusively in caves.
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;
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 ...
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.
Extensive research of stygofauna has been undertaken in countries with ready access to caves and wells such as France, Slovenia, the US and, more recently, Australia. Many species of stygofauna, particularly obligate stygobites, are endemic to specific regions or even individual caves. This makes them an important focus for the conservation of ...
Troglobites also require stable temperatures and high humidity, with the cave temperature typically being close to the annual surface temperature but with much less variation. Relative humidity in the caves is normally near 100%, and relative temperature is 71°F (around 22°C). [citation needed]
