Explanation:
Detailed explanation-1: -The larval stage of P. monodon consists of 6 nauplius, 3 protozoea, 3 mysis, and 3 or 4 megalopa substages, and the time required for each stage are about 1.5 days, 5 days, 4 to 5 days, and 6 to 15 days, respectively.
Detailed explanation-2: -The first larval stage called a nauplius emerges from the spherical egg and starts swimming up towards the surface. This naupliar stage goes through several moults, getting larger with each moult, and ultimately changes to a protozoea.
Detailed explanation-3: -Penaeid Shrimps pass through three larval stages before attaining the postlarval stage i.e., nauplius, zoea, and mysis.
