Examples of troglobites include cave millipedes, some beetles and cave spiders. Stygobites include blind crayfish, blind cavefish, blind cave salamanders and cave shrimp. This site has lots of information about bats. Human use of caves has come a long way throughout our history, from living space to hiding place and from commercial production to exploration. Despite the long existence of caves, we continue to learn from them and about them.
Caves are a valuable source for information about both the geological and historical past.
Fossils found in caves provide paleontologists with clues to the biological portion of the earth's history. Fossils of marine animals and plants that lived in the seas where the limestone was deposited are found imbedded in the bedrock. In addition, fossils of more recent terrestrial creatures which used the caves as homes or became trapped in sinkholes are sometimes found in cave passages. These include mammoth, mastodon, saber tooth cat, and giant sloth remains. Records of past human civilizations are found as cave artifacts, ranging from cave paintings and pottery of native and ancient peoples to the remnants of saltpeter mining from the American Civil War.
