Class: Malacostraca

Image copyrights: FAO

Max. size: 300-320 mm.

Color: Body flesh color, abdomen broad banded, appendages blue. In fresh specimens, especially in males the large chelipeds are deep peacock blue, passing into green on the palm and fingers. This colouration is absent from the coxal and basal joints and is deeper on the upper than on the under surface. The ambulatory legs are pale blue. The spines on the legs are deep blue at the base and orange towards the apex.

Rostrum over-reaching antennal scale or not, dorsal margin variably sinuous, rostral formula: 2-3 + 9-11/8-15, dorsal teeth unequally spaced. Branchiostegal suture not extending posteriorly behind hepatic spine. Telson with posterior apex over-reaching posterolateral spines. The telson tip is acutely pointed; the inner subterminal spinule on each side projects backwards beyond the outer one, but does not nearly reach the tip of the telson itself. 1st pereopod with chela less than 1/2 as long as carpus. 2nd pereopods subequal in length and similar in form, palm subcylindrical or somewhat compressed, movable finger clothed in dense pubescence on proximal 3/4 of length (in adults), fixed finger without pubescence, fingers dentate on proximal 1/2 of opposable margins (in adults), somewhat gaping in large males, 3/4 to quite as long as palm, palm without any dense pubescence, chela slightly to 1 3/4 times as long as carpus, palm 1/2 to quite as long as carpus, carpus slightly to nearly 1 1/2 times as long as merus, with indistinct longitudinal grooves. 3rd pereopods over-reaching antennal scale by less than length of dactyl, propodus bearing rather numerous spines or sharp scales. The large chelipeds are subcylindrical and either equal or subequal; half as long again as the body; a longitudinal pale line traverses the upper and lower surfaces of the palm, carpus and sometimes the merus. The joints are beset with broad-based spines which are less strongly developed on the ischium and the immobile finger. The palm is slightly compressed dorsoventrally, and is about the width of the distal end of the carpus.

Eggs are carried by females and hatch out in 20-21 days.
