This small fish was very bold, and I was surprised at how many times it would casually approach, sit on a rock, and look at me. The scalyhead sculpin (Artedius harringtoni) comes in a wide variety of colours, so its actual colouration is not a good indicator for identification. One possible indicator though is that orange gill membranes may be noticed as in this photo. Another identifying factor is that male scalyhead sculpins have a large flap of skin just behind each eye. The range of this sculpin is from northern Alaska to southern California.
