Brown Bullhead Catfish - Identification, Habitat & Biology #1536273 (License: Personal Use)

This accurate biological illustration depicts the brown bullhead (Ameiurus nebulosus), a common North American freshwater catfish distinguished by its dusky brown to olive body, dark mottling, and four pairs of barbels. The fish exhibits a robust, scaleless body, adipose fin, and slightly forked tail-adaptations for bottom-dwelling in slow-moving rivers, lakes, and ponds. Its nocturnal feeding habits and tolerance for low-oxygen environments make it ecologically resilient and widely distributed across eastern and central U.S. and Canada.
