Family Penacidae

Order Decapoda

Most edible prawns belong to the genera Penaeus and Metapenaeus.
They can be separated by the shape of their rostrum ("horn"). Penaeus has teeth on both rostral margins while Metapenaeus has them only on the upper margin.
They are occasionally green in colour due to their feeding on algae. They hide in sand or mud during the day and forage for all kinds of plant and animal matter at night.

They are important commercially, especially the tiger prawns, P. semisulcatus and P. monodon. These command high market prices and are farmed in some areas, especially near mangroves. Numerous attempts have been made to culture the animals. (Length up to 20cm).
