Comprimento de primeira maturação / Tamanho / Peso / Idade
Maturidade: Lm 8.3, range 8 - ? cm Max length : 20.0 cm CW macho/indeterminado; (Ref. 343); 21.5 cm CW (female); idade máx. registrada: 3.00 anos (Ref. 128174)
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.
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).
Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer.
