Restricted to deeper waters (Ref. 2786). Intraspecific predation observed in its early stages (Ref. 104081). Juveniles are observed to form aggregations known as "pods" on large kelp Macrocystis pyrifera. Young individuals are found around the holdfasts and stipes of this kelp (Ref. 104212) as well as on rocky bottoms in the subtidal nearshore (Ref. 104371). Juveniles are voracious and opportunistic omnivorous predators (Ref. 104371). Scavenger and predator (Ref. 113323). Also in Ref. 78676.
Life cycle: Females begin molting in late November to early December. Fertilization occurs right after oviposition. Embryogenesis lasts 9-10 months. Larval hatching occurs between mid-September and October. Embryos develop into lecithotrophic or facultative larvae, which passes through three zoeal and one megalopal stages, and later metamorphoses to the first benthic crab stage. Mating behavior: A precopulatory embrace occurs between an old-shelled male and a recently molted female. Females carry 5500-60000 eggs (Ref. 93013).
