what is an adaptation of a cave dwelling animal
List of troglobites Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism, reduced energy consumption, better food usage efficiency, decrease or loss of eyesight (anophthalmia), and depigmentation (absence of pigment in the integument). Conversely, as opposed to lost or reduced functions, many species have evolved elongated antennal and locomotory appendages, in order to better move around and respond to environmental stimuli. These structures are also full of chemical, tactile and humidity receptors. Troglobites commonly do not survive well outside caves and, therefore, cannot travel between separate cave systems. As a result, many troglobiotic species are endemic to a single cave or system of caves.[2][3][4][5]
Lascaux On September 12, 1940, the entrance to the Lascaux Cave was discovered by 18 year old Marcel Ravidat. Ravidat (died in 1995) returned to the scene with three friends, Jacques Marsal, Georges Agnel, and Simon Coencas, and entered the cave via a long shaft. The teenagers discovered that the cave walls were covered with depictions of animals.[7][8] Galleries that suggest continuity, context or simply represent a cavern were given names. Those include the Hall of the Bulls, the Passageway, the Shaft, the Nave, the Apse, and the Chamber of Felines. The cave complex was opened to the public on July 14, 1948.[9] By 1955, carbon dioxide, heat, humidity, and other contaminants produced by 1,200 visitors per day had visibly damaged the paintings. As air condition deteriorated fungi and lichen increasingly infested the walls. Consequently, the cave was closed to the public in 1963, the paintings were restored to their original state and a monitoring system on a daily basis was introduced.
