Alabama cavefish

The Alabama cavefish (Speoplatyrhinus poulsoni), is a critically endangered species of amblyopsid cavefish found only in underground pools in Key Cave, located in northwestern Alabama, United States in the Key Cave National Wildlife Refuge.[3] It was discovered underneath a colony of gray bats in 1967 and scientifically described in 1974.[4]
On any single visit to the cave, no more than 10 individuals of this fish have been observed, and scientists estimate fewer than 100 are left.[1] This fish is believed to be the rarest species of cavefish in the United States and one of the rarest of all freshwater fish. It exists in a fragile ecosystem based on nutrient-rich guano of the gray bat.[5] Researchers have failed to find the fish in any other location.[1]
