Feeding experiments show that P. monodon post-larvae can be infected by the HPV carried by Artemia, which implies the risk of rearing system contamination. [17] Parents-offspring transmissions are both reported by aquaculture farms in China and India, confirming the vertical transmission of HPV. [18] [19]
Penaeus monodon, commonly known as the giant tiger prawn, [1] [2] Asian tiger shrimp, [3] [4] black tiger shrimp, [5] [6] and other names, is a marine crustacean that is widely reared for food. Tiger prawns displayed in a supermarket
William Elford Leach erected the genus Megalopa in 1813 for a post-larval crab; a copepod post-larva is called a copepodite; a barnacle post-larva is called a cypris; a shrimp post-larva is called a parva; a hermit crab post-larva is called a glaucothoe; a spiny lobster / furry lobsters post-larva is called a puerulus and a slipper lobster post ...
Larvae are the feeding and growing stages and periodically undergo hormone-induced ecdysis, developing further with each instar, until they undergo the final larval–pupal moult. The larvae of many lepidopteran species will either make a spun casing of silk called a cocoon and pupate inside it, or will pupate in a cell under the ground.

From these eggs hatch zoeae, the first larval stage of crustaceans. They go through several larval stages in brackish water before metamorphosing into postlarvae, at which stage they are 0.28–0.39 in (7.1–9.9 mm) long and resemble adults. [5] This metamorphosis usually takes place about 32 to 35 days after hatching. [5]
In larvae, the genu of the palp has two setae. In post-larval stages, there are complex dermal structures consisting of a gland paired with a sensory seta (glandularia), possibly for defense against predators. [4] The palps of post-larval water mites vary depending on their diet.
Limnephilidae is a family of caddisflies with about 100 genera.They belong to the main lineage of case-constructing caddisflies, the Integripalpia or tube-case caddisflies. . The Limnephilidae is one of the most species-rich Trichoptera families of northern temperate regions, but only a few are known from tropical areas and the Southern Hemisphe
