• Cambarus tartarus

  Oklahoma Cave Crayfish

  Cambarus tartarus is a critically endangered cave-dwelling crayfish endemic to two caves in Delaware County, Oklahoma. Described in 1972, this species has one of the most restricted ranges of any North American crayfish. 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 contamination.
