Prawn Vs Shrimp: What's The Difference?

What are prawns?

Prawns are decapod crustaceans (10-legged) in the suborder Dendrobranchiata, characterized by branching gills and claws on three pairs of legs. The body of a prawn is longer and straighter than a shrimp's, without the pronounced bend that shrimp have. Prawns are typically larger than shrimp, ranging from 2-12 inches in length. Common varieties include tiger prawns, king prawns, and freshwater giant prawns. Prawns live in both freshwater and saltwater, with freshwater varieties being particularly large. The meat is slightly firmer than shrimp meat and has a mildly sweet flavor. In Asian and European cuisines, prawns are often featured as a centerpiece protein in curries, paella, and stir-fries due to their larger size.

What are shrimp?

Shrimp are decapod crustaceans in the suborder Pleocyemata, characterized by lamellar (plate-like) gills and claws on two pairs of legs. Shrimp have a distinctly bent or curved body shape that helps distinguish them from prawns. Shrimp are typically smaller than prawns, ranging from 1-4 inches in length, though jumbo shrimp can be larger. Common varieties include white shrimp, pink shrimp, brown shrimp, and rock shrimp. Shrimp live in saltwater and brackish water environments. The meat is tender and sweet, with a flavor that varies by species and water source. In American cuisine, shrimp are the dominant crustacean in dishes like shrimp scampi, shrimp cocktail, gumbo, and jambalaya. The US imports about 1.5 billion pounds of shrimp annually, mostly from Asian aquaculture.

How do prawns and shrimp compare?

Biologically, the differences are real but subtle: prawn gills branch; shrimp gills are plate-like. Prawn claws on three leg pairs; shrimp claws on two. Prawn bodies are straighter; shrimp bodies bend. In practice, these differences matter little for cooking. Size is the most practical difference: prawns are generally larger than shrimp. Flavor is similar: both have sweet, mild seafood taste, with prawns having slightly firmer texture. Price differs: prawns cost more per pound than shrimp due to the larger size requiring more growing time. In British English, 'prawn' is the standard term for what Americans call shrimp; British prawn cocktail is essentially American shrimp cocktail. In Asian cuisine, the distinction is sometimes maintained but often blurred.

Can you substitute one for the other?

Yes, prawns and shrimp substitute for each other in nearly all recipes with the only adjustment being cooking time based on size. Recipes calling for jumbo shrimp can use small prawns; recipes calling for tiger prawns can use jumbo shrimp. Adjust cooking time: smaller shrimp cook in 2-3 minutes per side; larger prawns need 3-5 minutes per side. The same cooking methods work for both: grilling, sauteing, boiling, steaming, and frying all produce similar results. Both cook through quickly when the flesh turns from translucent gray to opaque pink-white. Overcooking turns both rubbery; remove from heat as soon as the color change is complete. For paella, curry, scampi, or any seafood dish, prawns and shrimp work essentially identically.
