The tadpole madtom is a small North American madtom (family Ictaluridae). The species reaches about 13 cm and has a stocky, brownish body with a rounded tail, barbels and an adipose fin fused to the dorsal fin. It inhabits lakes and pools and backwaters with mud or detritus bottoms of lowland creeks and rivers. Its diet consists of midge larvae, isopods, amphipods and mayfly and caddisfly larvae. Like other madtoms it bears a venomous pectoral spine that can deliver a painful sting. The species is nocturnal and otherwise harmless to humans.
