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).

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.
The existence of the cave was first recorded by Alfred Howitt. [2] After heavy rainfall, the opening of the cave may be hidden by a waterfall, which has excavated a pool at its base. [2] The den was once rimmed with stalactites, but unfortunately these have been broken off as souvenirs by visitors over the years. Smaller stalactites may still ...
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.
The olm's body is snakelike, 20–30 cm (8–12 in) long, with some specimens reaching up to 40 centimetres (16 in), which makes them some of the largest cave-dwelling animals in the world. [ 13 ] [ 14 ] The average length is between 23 and 25 cm. [ 15 ] Females grow larger than males, but otherwise the primary external difference between the ...
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.
Ronald Reagan was president. The Nintendo Entertainment System was released in the U.S., along with the Sony Walkman. The Titanic wreckage was discovered. The ill-fated New Coke made its debut. So ...
Since the cave environment is dark, no plant life is performing photosynthesis, and food is mainly introduced from the outside world by other organisms. Limited food leads to low population density, which has been estimated for Amblyopsidae to be only about 0.005 to 0.150 animals per square meter.
