About Tonicella lokii R.N.Clark, 1999
Like most chitons of the genus Tonicella, Tonicella lokii has blue, white, purple, or black zig-zag lines across each of its eight valves. The background color of the valves is most often brown or red, but can also be bright blue, or yellow through orange. Its girdle is hairless, and ranges in color from brown to red or pink. The girdle has radiating bands, and often carries a broken yellow or white concentric line that alternates with these radiating bands.
