Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

North America: most of eastern USA and southeastern Canada in Atlantic, Great Lakes, Hudson Bay, Mississippi and Gulf basins as far as Manitoba, Montana, Wyoming, Colorado, Oklahoma, and Texas, but absent from southern Georgia and peninsular Florida; upper Pecos and Canadian River systems, New Mexico.

Biology     Glossary (e.g. epibenthic)

Inhabits rocky and sandy pools of headwaters, creeks and small rivers (Ref. 5723); mostly found in tiny, intermittent streams. Young feed on small aquatic invertebrates. Adults consume small fish, crayfish and other large invertebrates (Ref. 10294). One of the most common fishes in eastern North America (Ref. 5723).
