Crustaceans

Troglobites found only in base level streams include the endangered Kentucky Cave Shrimp (Palaemonias ganteri). The more adaptable cave crayfish Orconectes pellucidus occupies habitats ranging from base level to tiny streams, and can travel out of water if necessary. The troglophilic or partially cave adapted amphipod Crangonyx packardi, the crayfish Cambarus tenebrosus, the sculpin Cottus carolinae, and the springfish Chologaster agassizi often occur in organically rich situations. With the exception of sculpin, fish and crayfish are predators and the remaining species are primarily grazers.

Tuberculosis Hut in Mammoth Cave

In 1841, cave owner Dr. John Croghan believed the cave air might cure his patients suffering from tuberculosis. He brought 16 patients into Mammoth Cave that winter and housed them in stone and wood huts. After some perished, they left the cave, for of course the cave air offered no cure.
