Metapenaeus monoceros, a member of the Penaeidae family, is a medium-sized shrimp species. Male individuals typically reach a maximum total length of 15 cm, while females can grow up to 19.5 cm. The general size range for this species falls between 1.05 and 13.5 cm. Their appearance is characterized by a pale gray body with dark brown spots. The rostral and abdominal carenes exhibit a brown hue, while the antennae are red. The exoskeleton is covered with stiff material. Pereopods and pleopods share the same coloration as the body, sometimes appearing more vibrant. The distal section of the uropods displays a purple-blue color, and the outer edge of the exopodites is red. The rostrum of Metapenaeus monoceros is about the same length as the antennular peduncle’s tip and typically features 9 to 12 teeth. The carapace is equipped with robust antennal spines and smaller hepatic spines. A prominent ridge defines a well-marked postantennular groove that meets the cervical groove. The carina extending beyond the rostrum reaches the posterior margin of the carapace. The body’s coloration can vary, ranging from pinkish and greyish-green to whitish, all adorned with brown spots. The rostral and abdominal carenes maintain a brown color, while the antennae stand out in red. The telson has lateral edges lined with small spines of equal size, culminating in a single sharp point.
