Biology and Ecosystem
Following species of bats that inhabit the caverns: Indiana bat (Myotis sodalis), Gray bat (Myotis grisescens), Little brown bat (Myotis lucifugus), Big brown bat (Eptesicus fuscus), and the Eastern pipistrelle bat (Pipistrellus subflavus).
All together, these and more rare bat species such as the Eastern Small-footed Bat had estimated populations of 9–12 million just in the Historic Section. While these species still exist in Mammoth Cave, their numbers are now no more than a few thousand at best. Ecological restoration of this portion of Mammoth Cave, and facilitating the return of bats, is an ongoing effort. Not all bat species here inhabit the Cave; the red bat (Lasiurus borealis) is a forest-dweller, found underground only rarely.
Other animals which inhabit the caves include: Two genera of crickets (Hadenoecus subterraneus) and (Ceuthophilus stygius) (Ceuthophilus latens), a cave salamander (Eurycea lucifuga), two genera of eyeless cave fish (Typhlichthys subterraneus) and (Amblyopsis spelaea), a cave crayfish (Orconectes pellucidus), and a cave shrimp (Palaemonias ganteri)
In addition, some surface animals may take refuge in the entrances of the caves but do not generally venture into the deep portions of the cavern system.
