Benton County Cave Crayfish
Usually Found: Caves in Arkansas, USA (mostly in Benton County)
When we talk about creepy animals that live in caves, these guys need to be near the top for sure. They are native only to the state of Arkansas, in four different cave locations. The Benton County Cave Crayfish is sadly endangered, and due to its lack of mating, it is unknown how long it’ll survive. The species is around 48 millimeters or 1.8 inches long.
While they have adapted to groundwater environments, this is usually only within caves. This crayfish species lacks pigment, making it completely white and sort of translucent. It does have eyes, even if they are rudimentary. The body and claws have numerous stiff hairs and its rostrum is crested with small spines. It is theorized that we might not have very long to see the species in the wild unless something can be done to protect the population and encourage mating.
