Introducing the Genus Penaeus

A Significant Crustacean Group

The genus Penaeus encompasses a group of prawns, most notably including the giant tiger prawn (Penaeus monodon). This species holds considerable importance globally, being the most significant crustacean in worldwide aquaculture operations.^[1]

Biological Classification

Within the broader classification of marine life, Penaeus belongs to the order Decapoda, which includes all ten-footed crustaceans such as crabs, lobsters, and shrimp. Specifically, it falls under the suborder Dendrobranchiata, a group characterized by specific gill structures and reproductive strategies.

Taxonomic Revisions and Significance

A Shift in Classification

The taxonomic standing of the genus Penaeus has undergone significant revision. A notable proposition by Pérez Farfante and Kensley, based on detailed morphological differences, particularly in genital characteristics, led to a reorganisation of the genus.^[1] While this revision has been influential, it has not achieved universal acceptance within the scientific community.

Reassignment of Species

Following this proposed revision, numerous species previously classified under the genus Penaeus have been reassigned to newly established genera within the family Penaeidae. These include Farfantepenaeus, Fenneropenaeus, Litopenaeus, and Marsupenaeus. This taxonomic restructuring reflects a deeper understanding of the evolutionary relationships and distinct physical attributes among these prawn species.^[1]
