Description
The bullrout has a large head, and seven spines on the operculum. It has a big mouth with a protruding lower jaw. The spinous dorsal fin is slightly concave posteriorly and the last soft dorsal ray is attached by a membrane to the caudal peduncle. The body is covered with small scales, but the head is scaleless. Its colouration is variable from pale yellowish to dark brown, with blotches and marbling of dark brown, red-brown, grey, or black. These markings sometimes form broad, irregular bands. Bullrout may grow up to 30 cm in size, but are more commonly found at the 20-cm size.
Danger to humans and first aid
The dorsal, anal, and pelvic spines on a bullrout have venom glands on them, and should be handled with extreme care . A puncture wound from one of these spines can be excruciatingly painful. For immediate relief of pain associated with the sting of a bullrout, immerse the affected area in hot water.
