Inhabit pools with logs and other debris in low-gradient to moderate-gradient, small to large rivers. Also found in lakes and impoundments. Young occur in rocky and sandy runs and riffles (Ref. 5723). Juveniles feed on aquatic insect immatures in riffle areas (Ref. 10294).

Flathead catfish are carnivores that prey on many different types of animals, depending on size. They are known to eat crayfish, gizzard shad (Dorosoma cepedianum), insects and larvae, channel catfish (Ictalurus punctatus), drum (Aplodinotus grunniens), other flatheads (Pylodictis olivaris), green sunfish (Lepomis cyanellus) and carp. Insect larvae are the major prey type until an individual reaches approximately 100 mm in total length, at which point the diet expands to include crayfish and small fishes. Individuals above 250 mm in length feed almost exclusively on other fishes.
Animal Foods: fish; insects; aquatic crustaceans
Primary Diet: carnivore (Piscivore , Insectivore , Eats non-insect arthropods)
