Shrimps and prawns are types of shellfish seafood that are consumed worldwide. Prawns and shrimps are crustacea and are very similar in appearance with the terms often used interchangeably in commercial farming and wild fisheries. A 1990s distinction made in Indian aquaculture literature, which increasingly uses the term "prawn" only for the freshwater forms of palaemonids and "shrimp" for the marine penaeids that belong to different suborders of Decapoda.{{cite web |publisher=Indian Aquaculture Authority |url=http://aquaculture.tn.nic.in/pdf/farming.pdf |title=Shrimp Aquaculture and the Environment - An Environment Impact Assessment Report, chapter 2; IAA report |year=2001 |url-status=dead |archive-url=https://web.archive.org/web/20110716081932/http://aquaculture.tn.nic.in/pdf/farming.pdf |archive-date=2011-07-16 }} This has not been universally accepted.
In the United Kingdom, the word "prawn" is more common on menus than "shrimp", whereas the opposite is the case in North America. Also, the term "prawn" is loosely used for larger types, especially those that come 30 (or fewer) to the kilogram — such as "king prawns", yet sometimes known as "jumbo shrimp". In Britain, very small crustaceans with a brownish shell are called shrimps, and are used to make the traditional English dish of potted shrimps. Australia and some other Commonwealth nations follow this British usage to an even greater extent, using the word "prawn" almost exclusively. When Australian comedian Paul Hogan used the phrase, "I'll slip an extra shrimp on the barbie for you" in an American television advertisement,{{cite journal | author1 = Bill Baker | author2 = Peggy Bendel | name-list-style = amp | issue = Summer 2005 | url = http://www.atme.org/pubs/archives/77_1898_11926.cfm | title = Come and Say G'Day! | journal = Travel Marketing Decisions | publisher = Association of Travel Marketing Executives | access-date = December 21, 2007 | url-status = dead | archive-url = https://web.archive.org/web/20071104153701/http://www.atme.org/pubs/archives/77_1898_11926.cfm | archive-date = November 4, 2007 }} it was intended to make what he was saying easier for his American audience to understand, and was thus a deliberate distortion of what an Australian would typically say. They are also used in dishes where they are not the primary ingredient. The French term {{lang|fr|crevette}} is often encountered in restaurants.
All shellfish, including prawns and shrimps, are among the most common food allergens.{{cite web | title = Common Food Allergens | url = http://www.foodallergy.org/allergens/index.html | publisher = Food Allergy & Anaphylaxis Network | access-date = June 24, 2007 | url-status = dead | archive-url = https://web.archive.org/web/20070613040928/http://www.foodallergy.org/allergens/index.html | archive-date = June 13, 2007 }}
The Jewish dietary laws, kashrut forbid the eating of shellfish, including prawns and shrimps.[http://www.torah.org/advanced/shulchan-aruch/classes/chapter1.html Yoreh De'ah - Shulchan-Aruch] {{webarchive|url=https://web.archive.org/web/20120603170414/http://www.torah.org/advanced/shulchan-aruch/classes/chapter1.html |date=2012-06-03 }} Chapter 1, torah.org. Retrieved 17 June 2012. Meanwhile, in Islamic dietary law, the Shafi'i, Maliki, Hanbali and Ja'fari schools allow the eating of shrimp, while the Hanafi school does not.

As with other seafood, crustacea are high in protein but low in food energy. A shrimp-based meal is also a significant source of cholesterol, from 122 mg to 251 mg per 100 g of shrimp, depending on the method of preparation.{{cite web |url=http://www.dietaryfiberfood.com/cholesterol-shrimp.php |title=Cholesterol Content in Seafoods |access-date=January 7, 2007}} Shrimp consumption, however, is considered healthy for the circulatory system because the lack of significant levels of saturated fat in shrimp means that the high cholesterol content in shrimp actually improves the ratio of LDL to HDL cholesterol and lowers triglycerides.{{cite journal |url=http://www.ajcn.org/cgi/reprint/64/5/712.pdf |title=Effects of shrimp consumption on plasma lipoproteins |author=Elizabeth R.

Prawns are high in levels of omega-3s (generally beneficial) and low in levels of toxic mercury, with an FDA study in 2010 showing a level of 0.001 parts per million{{cite journal|doi=10.1016/j.marpolbul.2010.06.045|pmid=20633905|title=Mercury concentrations and omega-3 fatty acids in fish and shrimp: Preferential consumption for maximum health benefits|journal=Marine Pollution Bulletin|volume=60|issue=9|pages=1615–1618|year=2010|last1=Smith|first1=Katrina L.|last2=Guentzel|first2=Jane L.|bibcode=2010MarPB..60.1615S }} analysing only methylmercury.[https://web.archive.org/web/20090602034804/http://www.fda.gov/Food/FoodSafety/Product-SpecificInformation/Seafood/FoodbornePathogensContaminants/Methylmercury/ucm115644.htm Mercury Levels in Commercial Fish and Shellfish (1990–2010)] U.S. Food and Drug Administration.

Preparation
Preparing for consumption the smaller shrimp is done just by shelling, whereas for the larger prawns usually involves removing the head, shell, tail, and "sand vein". A notable exception is drunken shrimp, a dish using freshwater shrimp that is often eaten alive, but immersed in ethanol to make consumption easier.{{cite web|url=http://www.deependdining.com/2006/05/2-live-food-or-fresh-and-furious-live.html|access-date=May 20, 2016|title=2 Live food or the fresh and the furious. Live drunken shrimp & live lobster sashimi|author=Lin, E.|year=2006|publisher=Deep End Dining}}
To shell a prawn, the tail is held while gently removing the shell around the body. The tail can be detached completely at this point, or left attached for presentation purposes. Although the head and shell are generally removed before consumption, they are edible when cooked.{{Cite web |date=2017-09-07 |title=A Very Good, Very Crunchy Reason to Not Peel Shrimp |url=https://food52.com/blog/20444-recipes-with-shell-on-shrimp |access-date=2023-01-17 |website=Food52 |language=en-us}} Much of the flavor of prawns comes from the shell, so it is preferable to cook them before shelling, otherwise by adding the shells to the cooking stock prior to straining or by flash cooking the shells in the pan to extract the "juices".

Removing the "sand vein" (a euphemism for the digestive tract) is referred to as "deveining". This can be removed by making a shallow cut lengthwise down the outer curve of the prawn's body, allowing the dark ribbon-like gut to be removed with a pointed utensil. Special deveining tools are sometimes used, but knives, skewers, and even toothpicks can be used to devein.{{Cite web|url=https://whatscookingamerica.net/shrimptips.htm|title=Shrimp Hints and Tips|date=Sep 8, 2015|website=whatscookingamerica.net|accessdate=Dec 31, 2022}}{{Cite web|url=https://www.recipetips.com/kitchen-tips/t--1239/how-to-prepare-and-devein-shrimp.asp|title=How to Prepare and Devein Shrimp|website=www.recipetips.com|accessdate=Dec 31, 2022}} Alternatively, if the tail has been detached, the gut can be pinched at the tail end and pulled out completely with the fingers. On large prawns, the "blood vein" (a euphemism for the ventral nerve cord) along the inner curve of its body is typically removed as well. It is then rinsed under cold running water. Removing these "veins" is not essential, as it is not poisonous and is mostly tasteless.[http://www.heb.com/mealtime/FS-storeDeveinShrimp.jsp H-E-B's Guide on Storing and Deveining Shrimp] Deveining does slightly change the flavor and makes it more consistent.[http://mideastfood.about.com/od/tipsandtechniques/a/deveinshrimp.htm How to Devein Shrimp] Shrimp also sometimes consume small amounts of sand and so the vein might be gritty.

Recipes using shrimp form part of the cuisine of many cultures. Strictly speaking, dishes containing scampi should be made from the Norway lobster, also called Dublin Bay prawn or {{lang|Fr|langoustine}} in French — a crustacean c.{{convert|10|cm|in|sigfig=1|abbr=off}} long, more closely related to the lobster than shrimp — though in some places it is quite common for other prawns to be used instead.
Shrimp and prawns are versatile ingredients. Common methods of preparation include baking, boiling, frying, grilling, and barbequing. They are as delicate as eggs with regard to cooking time. Either cook them quickly, at a high heat for a very short time or else at a low cooking temperature for a long time, or if mixed into a dish, then added close to the end of cooking. When they are overcooked, they have a tough and rubbery texture.
Wet shrimp is commonly used as a flavoring and as a soup base in many Asian cuisines with shrimp curry being very popular in South Asia and Southeast Asia. Other recipes include bagoong, okonomiyaki, and poon choi. In the subject of Japanese sushi, shrimp has long been valued as the "king of sushi-dane", as its composition can be either raw or cooked, and its latter preparation has often been considered a good introduction or choice for those unfamiliar to eating sushi, especially dishes involving raw fish. In North America, fried shrimp is popular, as is jambalaya in the southern States. Shrimp are also found in Latin American and Caribbean dishes such as enchiladas and coconut shrimp. In Europe, prawns and especially {{lang|Fr|langoustines}} are very popular, forming a necessary ingredient in Italian {{lang|it|cacciucco}}, Portuguese {{lang|pt|caldeirada}}, Spanish {{lang|es|paella de marisco}}, and many other seafood dishes. Prawns are also consumed as salad, by frying, with rice, and as shrimp guvec — a dish baked in a clay pot — on the Mediterranean coast of Turkey.
Also, shrimps are fermented into shrimp paste and prawn sauce condiments in southeast Asia and China.{{cite web | url=https://www.thespruceeats.com/what-is-shrimp-paste-3217015 | title=Is Shrimp Paste the Right Addition to Your Thai Pantry? }}
Substitutes
Several alternatives have emerged, fostered by environmental and welfare concerns regarding the fishing and farming of shrimps. Plant-based alternatives often have soy or seitan as a main ingredient. They may also use konjac for the texture, and various other ingredients like seaweed.{{Cite web |date=2025-02-28 |title=What Makes Vegan Shrimp Bounce?

Marketing
{{main|Shrimp marketing}}
Shrimp are marketed and commercialized with several issues in mind. Most shrimp are sold frozen and marketed based on their categorization of presentation, grading, colour and uniformity.{{cite journal |author=Yung C.

{{main|List of shrimp dishes}}
Many various dishes are prepared using shrimp as a primary ingredient.
Ebiko, or shrimp roe, sometimes translated as "shrimp flakes", is used as an ingredient in the preparation of sushi.{{Cite web|url=http://www.koloajodo.com/2016/01/26/what-is-masago-ebiko-tobiko/|title=What is Masago?
