Description

The mountain madtom is a small catfish of the family Ictaluridae from the eastern United States, in the Ohio and Tennessee drainages. The species reaches about 13 cm and has a stocky, brown mottled body with barbels around the mouth. It inhabits clean, fast-flowing, rocky riffles and runs of small to large rivers, often near vegetation. The diet consists of larvae of aquatic insects, especially mayflies. Unlike most catfishes it bears a venomous pectoral spine: a sting gives a painful, bee-sting-like wound.
