flathead catfish -- Pylodictis olivaris
The flathead catfish has a broadly flattened head and a lower jaw that sticks out beyond the upper jaw. The rear margin of the tail fin is notched but not deeply forked, and the upper lobe of this fin has a white tip. The flathead may reach five feet in length and live in a variety of stream types, lakes and impoundments, often near drifts, submerged logs or in pools. This fish is solitary in habits. It feeds at night, mainly on fish and crayfish. Spawning occurs in late June and July. The yellow egg mass is placed in a depression created by the adults. The adults stay with the eggs until hatching, fanning them with their fins to increase oxygen flow and remove silt. The average life span is 12-15 years.
