; пределы глубины 0 - 50 m (Ref. 290). Temperate
Eastern Pacific: Canada and Mexico.
Length at first maturity / Size / Вес / Возраст
Maturity: Lm ?  range ? - ? cm Max length : 2.4 cm TL самец/пол неопределен; (Ref. 290)
Body: Elongate oval. Tegmentum color: Variable, may be orange, dark red, greyish brown, with or without large patches of black; Some brightly colored specimens have tail valves that are completely black. Sculpture: Radiating, often branching rows of large granules on the head valve (30-36 rows) and lateral areas (5-8), the rows usually not reaching the apex. Central areas: Fine, close-set lines of granules, the lines becoming larger and further apart towards the outer margins of the valves. Postmucronal area: Scarce, scattered granules. Mucro: Submedian in younger specimens; subterminal in full-grown specimens. Girdle: Rather narrow, evenly orange-brown or greyish brown; with spicules of varying types and sizes; a marginal fringe of straight spicules (290). Valves: Range from bright orange with black tail valve (and white spot) to ashy green with same markings (Ref. 296).
Life cycle and mating behavior

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.
