Neosho Madtom

The Neosho madtom (Noturus placidus) is a small North American freshwater catfish. It has been listed as a near-threatened species in the United States since 1996 by the International Union for Conservation of Nature and as a federally threatened species under the Endangered Species Act of 1973 since June 1990.

The Neosho madtom has features characteristic of all North American catfish, including scaleless skin and a relatively large head with sensory barbels. Adults average less than 3 in (8 cm) in length. They have a brownish midline stripe and an overall mottled appearance. The light-colored edge of the adipose fin is the best characteristic to distinguish it from similar species.
