Polyplacophora | Chitonida
Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 0 - 600 m (Ref. 290). Temperate
Pacific Ocean. Temperate to polar.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 32.5 cm TL male/unsexed; (Ref. 865)
Valves: Pure white; completely covered by what appears to be coarse maroon leather. Large white valves (Ref. 296).
Fisheries: The foot of the Gumboot Chiton is sometimes eaten in the same manner as the abalone (Ref. 296). Depth ranges from intertidal to 600 m. Inhabits a variety of bottom-types, but prefer stone and pebble (Ref. 290); at some periods in their life cycle, they teem into the intertidal zone (Ref. 339). Often found on the beach (Ref. 296). 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).
