Penaeid and sergestid shrimps

Dendrobranchiata is a suborder of decapods, commonly known as prawns (though this may be ambiguous). There are 540 extant species in seven families, and a fossil record extending back to the Devonian. They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills (hence their scientific name Dendrobrachiata) and by the fact that they do not brood their eggs, but release them directly into the water. They may reach a length of over 330 millimetres (13 in) and a mass of 450 grams (1.0 lb), and are widely fished and farmed for human consumption.
