Color: adult male dorsally purplish red, more accented on proto-, meso-, and metagastric areas and at base of lateral spines and anterolateral teeth; branchial region and anterolateral teeth obscure maroon; dorsal surface of all legs purplish red with intense orange red on articulations; inferior portions of merus, carpus, and fingers of chelipeds intense violet; internal and external portion of chelae as well as remaining ventral aspect of animal white with tints of soft purple.

Biology     Glossary (e.g. epibenthic)

Maximum depth from Ref. 105697. Inhabits estuaries and shallow oceanic littoral zones, especially in association with mangroves and near river mouths, down to 8 m (Ref. 367). Possibly freshwater (Ref. 95880). Feeds on mollusks, other bottom invertebrates, fishes, carrion and detritus (Ref. 367). Digs the clam D. denticulatus out of the sand with one of its claws then handles and cracks its shell (Ref. 106085). Members of the order Decapoda are mostly gonochoric. Mating behavior: Precopulatory courtship ritual is common (through olfactory and tactile cues); usually indirect sperm transfer (Ref. 833).
