Tartarocreagris texana is a species of arachnid in family Neobisiidae.
 It is endemic to Texas in the United States, where it is known from only two caves in Travis County.
 It is a federally listed endangered species of the United States.
The site comprises two caves, called 'Banwell Bone Cave' and 'Banwell Stalactite Cave', which lie within the grounds of a large house, at the western end of Banwell Hill.
 The caves contain barite deposits, which are found in greater abundance and variety here than at any other site in the Mendip Hills, and are used as a hibernation site by greater horseshoe bats ("Rhinolophus ferrumequinum").
Eupolybothrus cavernicolus is a species of centipede so far only found in two caves near the village of Kistanje, in Šibenik-Knin County, Croatia.
Badger Pot and Pigeon Pot are two caves found in the Karst topography on the eastern slopes of Cuilcagh Mountain, south of Florencecourt Forest Park, County Fermanagh, Northern Ireland.
Procambarus nueces, sometimes called the Nueces crayfish, is a species of crayfish in the family Cambaridae.
 It is endemic to the Atascosa River in Atascosa County, Texas.
 It was described from four individuals, and only two further individuals have been found since.
Neoleptoneta microps is a rare species of spider in the family Leptonetidae known by the common name Government Canyon bat cave spider.
 It is endemic to Texas in the United States, where it is known from two caves in Bexar County.

Georissa is a genus of minute land snails, terrestrial gastropod mollusks in the family Hydrocenidae.
 Although the species are best known for living on the surface of limestone rocks, they are often also found in and on the vegetation and on non-calcareous rocks.
 One species, "Georissa filiasaulae", is cavernicolous.
 It is only known from two caves in the Sepulut area of Sabah, Malaysian Borneo, where its above-ground sister species, "Georissa saulae", inhabits the rocks outside of the cave, and is connected to the cave snail via narrow zones of hybridization at the cave entrances.
 Possibly, "G. filiasaulae" has evolved without ever having been fully separated from its ancestor, a process known as speciation-with-gene-flow.
Marion County is a county located in the U.S. state of Florida.
