The IUCN assessed it as Critically Endangered in 2010, noting an extremely high risk of extinction in the immediate future due to its tiny geographic range and vulnerability to groundwater .

As a troglobitic species, it likely exhibits typical cave-adapted features including reduced pigmentation and elongated appendages, though specific diagnostic morphological characters distinguishing it from are not documented in available sources.
Habitat
Exclusively subterranean; restricted to two caves in Delaware County, Oklahoma. Dependent on groundwater systems with stable aquatic conditions typical of solution caves in karst topography.
Distribution
to two caves in Delaware County, Oklahoma, United States. This represents one of the most geographically restricted ranges of any North crayfish .
Ecological Role
As a troglobitic , likely functions as a scavenger and within the limited aquatic cave , processing matter that enters the groundwater system.
