Body elongate, compressed, with a deep caudal peduncle. Head pointed, with concave dorsal profile becoming convex in front of dorsal fin. Mouth large, slightly oblique, upper jaw reaching to behind eye; teeth villiform, no canines present. Lower edge of pre-operculum with a strong spine; operculum with a small spine and with a serrated flap above origin of lateral line. Lower first gill arch with 16 to 17 gillrakers. Scales large, ctenoid. Dorsal fin with 7 to 9 spines and 10 to 11 soft rays; a very deep notch almost dividing spiny from soft part of fin; pectoral fin short and rounded, several short, strong serrations above its base; dorsal and anal fins both have scaly sheaths. Anal fin rounded, with 3 spines and 7 to 8 short rays. Caudal fin rounded. Colour in two phases, either olive brown above with silver sides and belly (usually juveniles) or green/blue above and silver below. No spots or bars present on fins or body.

FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED
The giant tiger prawn inhabits the coasts of Australia, South East Asia, South Asia and East Africa.
Similar to all penaeid shrimp, the rostrum well developed and toothed dorsally and ventrally. Carapace without longitudinal or transverse sutures. Cervical and orbito-antennal sulci and antennal carinae always present. Hepatic and antennal spines pronounced. Pterygostomain angle round. Stylocerite at first antennular segment. Basial spines on first and second pereiopods and exopods on the first to fourth pereiopods usually present. No fixed subapical spines on telson. Adrostral sulcus and carina are short, not reaching posteriorly beyond midlength of carapace. Gastrofrontal carina absent. Females have closed-type thelycum. Petasma in male symmetrical with thin median lobes. The most distinct features for identification of this species are: fifth pereiopods without exopod; hepatic carina horizontally straight; and gastroorbital carina occupying the posterior half of the distance between hepatic spine and postorbital margin of carapace. Depending on substratum, feed and water turbidity, body colours vary from green, brown, red, grey, blue and transverse band colours on abdomen and carapace are alternated between blue or black and yellow. Adults may reach 33 cm in length and females are commonly larger than males.

Rostrum moderately long with 7-10 dorsal and 2-4 ventral teeth. In mature males petasma symmetrical and semi-open. Spermatophores complex, consisting of sperm mass encapsulated by sheath. Mature female has open thelycum. Six nauplii, three protozoeal, and three mysis stages. Coloration normally translucent white, but can change depending on substratum, feed and water turbidity. Maximum size 23 cm, with maximum CL of 9 cm. Females commonly faster growing and larger than males.

Body long, latterly flattened with no scales. Head relatively small. Mouth broad with small sharp teeth on jaw, vornerine and palatal bones. Eyes relatively large. Two pairs of barbels, upper shorter than the lower. Fins dark grey or black. Six branched dorsal-fin rays. Gill rakers normally developed. Young fish have black stripe along lateral line and another long black stripe below lateral line; large adults uniformly grey but sometimes with greenish tint and sides silvery. Dark stripe on middle of anal fin; dark stripe in each caudal lobe; small gill rakers regularly interspersed with larger ones.
