Short description Morphology

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.

Biology     Glossary (e.g. epibenthic)

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, 125338). 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). Spawns throughout the year, with peak from February to July (Ref. 116211).

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.
