Bullhead


Ameiurus melas

Species Overview


Physical Characteristics

Bullheads are compact, muscular catfish with smooth, scaleless bodies covered in protective mucus. Their distinctive flat head houses 8 sensitive barbels that function as both taste and smell organs, helping them locate food in murky water. The body tapers from a broad head to a rounded tail fin – never forked like channel catfish.

Coloration varies by species from yellow-green to dark brown, often with mottled patterns. Sharp, venomous spines in the dorsal and pectoral fins lock into place when threatened, making them difficult for predators to swallow.
