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]
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]
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.
In the caves of Southwest China, a tiny, fuzzy, multi-legged creature moves around in the dark. The male of the species catches the eye of a female clinging to the cave walls and coaxes her over ...
He named it Leptodirus Hochenwartii after the donor, and also gave it the Slovene name drobnovratnik and the German name Enghalskäfer, both meaning "slender-necked (beetle)". [6] The article represents the first formal description of a cave animal (the olm, described in 1768, wasn't recognized as a cave animal at the time). Subsequent research ...
The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 cm (2.0 in) long in body and 10 cm (3.9 in) for the legs. The bodies of early instars may appear translucent. As their name suggests, cave crickets are commonly found in caves or old mines.
A cave is an unusually well-defined ecological habitat in terms of its nature, time, and place. Accordingly, it is not surprising that a number of insects permanently inhabit caves, especially at the deepest levels, and are markedly specialised for niches in some of the extreme conditions.
Cavefish or cave fish is a generic term for fresh and brackish water fish adapted to life in caves and other underground habitats. Related terms are subterranean fish, troglomorphic fish, troglobitic fish, stygobitic fish, phreatic fish, and hypogean fish.
