Length at first maturity / Size / Weight / Age

Maturity: Lm ?  range ? - ? cm Max length : 22.0 cm CL male/unsexed; (Ref. 435)

Biology     Glossary (e.g. epibenthic)

Maximum carapace width: 18.0 cm. Maximum depth from Ref. 114133. Occurs from the sublittoral area (Refs. 435, 106904) to depths of about 90 m (Ref. 106904), on rocky bottoms with algae (Ref. 435). Juveniles are predominantly found in shallow waters with mixed hard-and-soft bottoms. Adults live in deeper areas (Ref. 106904).

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

Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
