Cryptobranchus alleganiensis bishopi
The Ozark hellbender is a strictly aquatic amphibian found in Ozark streams of southern Missouri and northern Arkansas. This subspecies of hellbender is listed as endangered because a rapid decline in numbers and range have left only small, isolated populations. Also, the hellbenders (Cryptobranchus alleganiensis), including both the Ozark hellbender and the eastern hellbender, have been included in Appendix III of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to protect both subspecies from declines due to international trade.
