The brown bullhead is a catfish with a sharp, venomous spine on its fins. It lives in lakes, ponds and slow streams across North America, and it is important to the Ojibwe people, who see it as one of their clan symbols.1

When attacked, the bullhead stiffens the sharp spine on the front edge of its dorsal and pectoral fins. While doing this, it releases venom that stings and burns the predator.1

Its fin spines can sting and burn, which is its main defence against predators. Treat any caught fish with care and avoid handling its spines.1

When attacked, it stiffens its fin spines to make it harder for a predator to swallow it, and releases venom to sting and burn.1

Eziokwu

It can survive very low oxygen levels, down to 0.2 ppm, and even heavily polluted water.1

Its spines can produce venom, which is unusual for a catfish species that is otherwise common and widely eaten.1

The brown bullhead is one of six beings in Ojibwe tradition that came out of the sea to form the original clans.1

Both males and females are known to eat their own eggs at times.1
