There might be as few as one hundred Alabama cavefish other side full of vibrancy today. This makes the species the rarest fish known to science, as well as one of the most endangered.
The Alabama cavefish is teetering on the edge of extinction. One of the crux explanations is since it is only found in Key Cave, which lies on the shore of manmade Pickwick Lake on the northern bank of the Tennessee River. It may have occurred in other caves in the past, but repeated searches have failed to find any of these fish. In addition, some of the other caves were flooded when Pickwick Lake was created.
