Maturity: Lm ?  range ? - ? cm Max length : 3.8 cm TL male/unsexed; (Ref. 281)
Maximum Total Length: 3.8 centimeters. Body: Elongated; has girdle that covers most of the valves. Valves: Have four clumps of long, glassy bristles near the anterior valve and one on each side of the other valves. Clumps: Set in cuplike collars of the girdle. Pustules: Tiny, round, sharply raised; covering end valves and lateral areas of middle valves. Dorsal longitudinal ridge: Raised, narrow, distinct and smoothish except for very fine pinpoints. Lower edge of the girdle: Dense fringe of brown or bluish bristles (Ref. 281).
Upper sublittoral, under stones and coral rubble (Ref. 2022, page 123). Members of the class Polyplacophora are mostly gonochoric. Life cycle: Eggs hatch into lecitotrophic planktonic trocophore larvae (no veliger stage) which later metamorphose and settle on the bottom as young adults (Ref. 833).
