Acanthochitonidae
Environment: milieu / climate zone / depth range / distribution range
Ecology
Benthic; depth range 0 - 60 m (Ref. 127878). 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).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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.
