The Caridea, commonly known as caridean shrimp or true shrimp (from Ancient Greek καρίς, καρίδος (karís, karídos, "shrimp"), are an infraorder of shrimp within the order Decapoda. This infraorder contains all species of true shrimp. They are found widely around the world in both fresh and salt water. Many other animals with similar names – such as the mud shrimp of Axiidea and the boxer shrimp of Stenopodidea – are not true shrimp, but many have evolved features similar to true shrimp.

Krill (Euphausiids) (: krill) are small and exclusively marine crustaceans of the order Euphausiacea, found in all of the world's oceans. The name "krill" comes from the Norwegian word '''', meaning "small fry of fish", which is also often attributed to species of fish.

A shrimp (: shrimp (US) or shrimps (UK)) is a common name typically used for crustaceans with an elongated body and a primarily swimming mode of locomotion – usually decapods belonging to the Caridea or Dendrobranchiata, although some crustaceans outside of this order are also referred to as "shrimp".

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 and a mass of , and are widely fished and farmed for human consumption.

Jasus is a genus of spiny lobsters which live in the oceans of the Southern Hemisphere. They have two distinct "horns" projecting from the front of the carapace, but lack the stridulating organs present in almost all other genera of spiny lobsters. Like all spiny lobsters, they lack claws, and have long stout antennae which are quite flexible.

Acetes is a genus of small prawns that resemble krill, which is native to the western and central Indo-Pacific, the Atlantic coast of the Americas, Pacific coast of South America and inland waters of South America. Although most are from marine or estuarine habitats, the South American A. paraguayensis is a fresh water species. Several of its species are important for the production of shrimp paste in Southeast Asia, including Acetes. japonicus, which is the world's most heavily fished species of wild shrimp or prawn in terms of total tonnage and represent the majority of non-human animals kil
