Identification Tips

1. 1

   Coloration and Pattern

   Look for the reddish-brown to olive-green body with mottling and banding. The intensity and specific hues can vary greatly depending on the local environment.

2. 2

   Head and Cirri

   Observe the large head and the presence of numerous fleshy cirri, particularly on the snout, around the eyes, and along the lateral line. These are more pronounced than in many other sculpins.

3. 3

   Lateral Line Scales

   A key diagnostic feature is the distinct band of scales along the lateral line, which is separated from the dorsal fin base by a naked (scaleless) strip. These scales are often larger and rougher than any other scales on the body.
