Maturity: Lm ?  range ? - ? cm
Minimum depth from Ref. 1726. Intertidal to shallow subtidal. Found under medium-sized granite rocks or dead coral slabs, slightly buried in coarse sand (Ref. 1726). Most chitons are microphagous feeders that consume fine algae and other organisms they scrape via their radula (Ref. 833).
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.
