This contrasts with the related Isopoda, which have a single kind of thoracic leg. By the 1960s, steel and fibreglass hulls further strengthened shrimp boats, so they could trawl heavier nets, and steady advances in electronics, radar, sonar, and GPS resulted in more sophisticated and capable shrimp fleets.

The Natantia or swimmers included the shrimp. Shrimp: a small free-swimming crustacean with an elongated body, typically marine and frequently of commercial importance as food. That creates problems with shrimp-like species that are not small. In the earlier years of marine shrimp farming the preferred species was the large giant tiger prawn. The long antennae help the shrimp orient itself with regard to its immediate surroundings, while the short antennae help assess the suitability of prey. Commercially important in Australia, Pakistan and the Persian Gulf. All of them are decapods; most of them belong to the Dendrobranchiata and four of them are penaeid shrimp. The shell which protects the cephalothorax is harder and thicker than the shell elsewhere on the shrimp and is called the carapace. Trawled in Asia where it is sold frozen.
