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 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 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.
Biospeleology, also known as cave biology, is a branch of biology dedicated to the study of organisms that live in caves and are collectively referred to as troglofauna. Biospeleology as a science [ edit ]
A sexually mature adult axolotl, at age 18–27 months, ranges in length from 15 to 45 cm (6 to 18 in), although a size close to 23 cm (9 in) is most common and greater than 30 cm (12 in) is rare. Axolotls possess features typical of salamander larvae, including external gills and a caudal fin extending from behind the head to the vent.
The cave swiftlet or linchi swiftlet (Collocalia linchi) is a species of swift in the family Apodidae. It is found on the Indonesia islands of Sumatra, Java and Bali. It is a woodland species and nests in caves. The Bornean swiftlet was considered a subspecies, but is now usually considered distinct.
The title of the Man or Astro-man? song "Many Pieces of Large Fuzzy Mammals Gathered Together at a Rave and Schmoozing with a Brick" is based on this song.. A quotation in the Karl Edward Wagner novel Bloodstone (1975) pays tribute to the song: "several species of small furry animals gathered together in cave and grooving with a pict."
This crayfish was first described to science as a new species in 1987. [3] There has been little formal study of this species due to its rarity. [5]It has been postulated that the four subterranean crayfish species inhabiting the Ozarks, including Cambarus aculabrum, derive from a common epigean ancestor species that gained access to a historic cave channel in the Ozark Plateau.
