Shrimp vs Prawns: Key Differences Explained
Shrimp and prawns are both crustaceans, but they belong to different suborders: shrimp to Pleocyemata and prawns to Dendrobranchiata. This means they have distinct gill structures, leg shapes, and reproductive methods.
At the seafood counter, the terms are swapped depending on where you shop. In the US, “shrimp” labels everything, while UK and Australian menus call the larger ones “prawns,” so diners assume size alone tells them apart.
Key Differences
Shrimp have a pronounced bend in their bodies, one pair of clawed legs, and plate-like gills. Prawns stay straighter, sport three pairs of claws, and use branching gills. Shrimp carry eggs under their tails; prawns release them into open water.
Which One Should You Choose?
For quick stir-fries and popcorn bites, choose shrimp—cooks faster and stays tender. Pick prawns for grilled skewers or curries; their firmer meat holds bold spices and won’t curl as tightly, giving a meatier bite.
Are prawns always bigger than shrimp?
Not always. Some shrimp species outsize certain prawns; the label depends on regional naming, not guaranteed size.
Can I substitute shrimp for prawns in recipes?
Yes, adjust cook time—shrimp finish in 2–3 minutes, prawns need 4–5—to avoid rubbery texture.
Do prawns taste stronger than shrimp?
Prawns carry a slightly sweeter, richer flavor, but the difference is subtle once sauces and marinades are added.
