Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 16.0 cm WD male/unsexed; (Ref. 367); 12 cm WD (female)
Carapace almost twice as broad as long; 9 teeth on moderately arched anterolateral margin (including outer orbital tooth and strong lateral spine) tending to be acuminate especially in outer part of row, with tips directed outward; front (excluding inner orbital angles) bearing 4 well-developed teeth, lateral pair moderately acute. Marginal slopes of convex dorsal surface smooth and glistening (when wet), central part and transverse lines variably granulate. Pincers granulate on ridges, fingers of major hand heavily toothed; fifth legs flattened in form of paddles. Male with T-shaped abdomen reaching to anterior 1/4 of thoracic sternite 4; slender first pleopods sinuously curved overlapping in 2 places proximally, diverging distally then recurving to termination near midline and tip of telson, armed distally with dorsolateral band of large and small retrogressive spinules. Color: carapace olive green with variable tints of brown and blue distally, articulations and spines of legs orange and blue; underparts cream and light yellow with suffusion of light blue.
Inhabits brackish to occasionally fresh waters containing much silt and decomposing organic material, usually below 16â€° salinity, on sandy and muddy bottoms and among roots of mangroves (Ref. 367). 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).
