Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
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).
