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.
