Check this out. These shrimps live right near my former home state of Ohio. Well, they are in Kentucky, but it's only across the river))). The Kentucky cave shrimp or Palaemonias ganteri is an eyeless and completely pigmentless troglobite specie. This amazing shrimp lives in caves in the Warren County of Kentucky. It has not pigment or eyes, just like many other troglobite species of animals.
It's main habitat is exclusively in underground streams of caves. Kentucky cave shrimp can easily be found in Mammoth Cave National Park if you look around. It feeds mainly on sediments that are washed into the cave by the movement of groundwater. Unfortunately, as with many other cave species, this cave shrimp is endangered. There is no chance of getting this guys for your shrimp tank. I guess, if you have a bunch of money, you can pay someone to smuggle it out of the cave. However, you would be able to brag about having, or you would get arrested)))
Here is some internet inf on on Palaemonias ganteri
The Kentucky cave shrimp was registered as an endangered species under the Endangered Species Act in 1983, and was included on the IUCN Red List as Endangered in 1994. There are currently only several thousand remaining. It is mostly threatened by contaminated groundwater running into its habitat. Several nearby communities either have inadequate sewage treatment facilities or lack such facilities altogether. An additional potential threat is the entry of contaminants from traffic accidents and roadside businesses. One incident in 1979 caused the death of aquatic cave organisms in a part of the Mammoth Cave system, and in a 1980 incident, a truck carrying toxic cyanide salts overturned on Interstate 65, just south of Mammoth Cave Nation
