Acanthochitona spiculosa

This one and one-half inch chiton is elongate and has a girdle that covers most of the valves. There are four clumps of long, glassy bristles near the anterior valve and one on each side of the other valves. The clumps are set in cuplike collars of the girdle. The end valves and lateral areas of middle valves are covered with tiny, round, sharply raised pustules. The dorsal longitudinal ridge is raised, narrow, distinct and smoothish except for very fine pinpoints. The lower edge of the girdle has a dense fringe of brown or bluish bristles. Syn: Acanthochitona astrigera (Reeve, 1847)
