Penaeus

Penaeus is a genus of prawns, including the giant tiger prawn (P. monodon), the most important species of farmed crustacean worldwide.

Taxonomy
The genus has been reorganised following a proposition of Pérez Farfante and Kensley based on morphological differences, in particular the genital characteristics of these animals, although this revision has not been universally accepted. Following the revision, many species formerly in the genus Penaeus (members of which are listed to the right) have been reassigned to new genera in the family Penaeidae: Farfantepenaeus, Fenneropenaeus, Litopenaeus, and Marsupenaeus. The following table gives an overview:

A few more species that are sometimes given as Penaeus spp. are actually assigned to the genus Melicertus:
