Short description Morfologi

Carapace finely granulose, regions just discernible; 9 teeth on each anterolateral margin, the last tooth 2 to 3 times larger than preceding teeth. Chelae elongated in males; larger chela with conical tooth at base of fingers; pollex ridged. Color: olive to dark green, with 3 prominent maroon to red spots on posterior 1/3 of carapace. Easily distinguished from other species by its very distinct color markings.

Biologi     Ordlista (t.ex. epibenthic)

Maximum length (female) from Ref. 119750. Occurs from the intertidal zone (especially juveniles) to depths of 30 m (Ref. 343). Subtidal (Ref. 106854). Inhabits sandy to sandy-muddy substrates (Refs. 343, 106287, 125338), in bays and estuaries (Ref. 106287). Also in brackish water (Ref. 801). Subtropical and tropical climates (Ref. 343). Mainly a predator of sessile and slow-moving benthic macroinvertebrates (Ref. 102720); may be a scavenger (Ref. 100855). Omnivore (Ref. 116259).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | 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.
