Noturus fasciatus
The saddled madtom (''Noturus fasciatus'') is a rare freshwater fish native to the U.S. state of Tennessee. It was first described as a species separate from ''Noturus crypticus'' in 2005.〔Burr, M. Eisenhour, D. Grady, J. 2005. Two new species of Noturus (Siluriformes : Ictaluridae) from the Tennessee River drainage: Description, distribution, and conservation status. Copeia. 2005. 4: 783-802〕 It is restricted to the Duck River system and is also found in two minor tributaries on the lower section of the Tennessee River. This species dwells in small to medium-sized streams where they can be found under gravel, rubble, and slab rock. They feed mostly on insects such as: stone, cattus and mayfly larvy.〔Noturus fasciatus. Fishbase. Retrieved 2011- 11- 18〕
==Geographic distribution==
The saddled madtom is found in the Duck River system and two minor tributaries of the Tennessee River in the western part of Tennessee〔 and has not yet been found in other streams or states. It is believed that this species can be found in neighboring streams and river systems but until proper research is conducted, it remains a theory.〔Burr, M. Cook, K. Eisenhour, D. Taylor, C. 1996. Conservation status review of the saddled madtom in the Duck River system, Tennessee. Journal of the Tennessee Academy of Science. 1996. 71. 2: 41-46〕
