What Are Shrimp and Prawns?
Both shrimp and prawns belong to the decapod family, meaning they have 10 legs. However, they come from different sub-orders:
- Shrimp: Belong to the sub-order Pleocyemata
- Prawns: Belong to the sub-order Dendrobranchiata
Although they may look similar, shrimp and prawns differ in their habitats, anatomy, and culinary uses.
Key Differences Between Shrimp and Prawns
1. Anatomy
The anatomy of shrimp and prawns varies, particularly in their legs, gills, and body structure:
- Legs:
- Shrimp have claws on two of their five pairs of legs.
- Prawns have claws on three pairs, giving them slightly longer legs than shrimp.
- Gills:
- Shrimp have plate-like (or lamellar) gills.
- Prawns have branching (or dendrobranchiate) gills, contributing to their classification differences.
- Body Segments:
- In shrimp, the second segment of their thorax overlaps the first and third segments, giving them a distinct body curve.
- Prawns have a more straightforward body structure, with each segment overlapping the next like a plate.
These structural differences are important in scientific classification and contribute to the unique appearance of each species.
2. Habitat and Distribution
- Shrimp are often found in saltwater environments, such as oceans and seas, although some species inhabit freshwater.
- Prawns are usually found in freshwater habitats, such as rivers and lakes.
The environmental differences can influence taste and texture, making prawns slightly sweeter and more delicate than shrimp in some cases.
3. Size Differences
While the terms are often used interchangeably, prawns are generally larger than shrimp. However, this is not a strict rule, as there are small species of prawns and large varieties of shrimp, such as tiger prawns or spot prawns.
4. Culinary Differences and Taste
From a culinary perspective, shrimp and prawns have slight taste and texture differences:
- Shrimp:
- Typically have a firmer, meatier texture.
- Commonly used in quick-cooking methods like sautéing, grilling, and boiling.
- Shrimp are more likely to become rubbery if overcooked due to their smaller size.
- Prawns:
- Often considered sweeter and more tender.
- Better suited to recipes where they can be grilled or roasted whole.
- Due to their larger size, they have a slightly longer cooking time.
How to Choose Between Shrimp and Prawns for Cooking
Taste and Texture Preferences
When choosing between shrimp and prawns, consider their subtle taste and texture differences:
- Shrimp have a firmer bite, making them ideal for dishes where texture is essential, such as in shrimp cocktails or salads.
- Prawns are generally sweeter and work well in delicate recipes, like prawn curries or light seafood pastas.
Cooking Tips for Shrimp and Prawns
When cooking shrimp or prawns, timing is key:
- Shrimp cook quickly, usually in a few minutes. Overcooking can lead to a rubbery texture.
- Prawns have a slightly longer cooking time, especially larger varieties. They are better suited to grilling and roasting where they can retain their juiciness and sweetness.
Best Recipes for Shrimp and Prawns
Some popular cooking methods and dishes for each include:
- Shrimp:
- Sautéed or boiled for shrimp cocktails.
- Grilled or roasted for tacos and seafood salads.
- Prawns:
- Grilled whole or skewered for barbecue dishes.
- Slow-cooked in sauces like curries or seafood stews.
Common Misconceptions About Shrimp and Prawns
Are Shrimp and Prawns the Same?
Although often labeled interchangeably, shrimp and prawns are different species with distinct anatomical and environmental differences. They are both crustaceans, but their classification in different sub-orders reflects unique physical traits.
Why Are Prawns Often Larger?
While prawns tend to be larger, there are large shrimp species (like tiger shrimp) that can match the size of prawns. When ordering at a restaurant or shopping at the seafood counter, it’s essential to consider the labeling, as “jumbo shrimp” may still be smaller than prawns.

| Size | Generally smaller | Typically larger |
| Habitat | Primarily saltwater | Primarily freshwater |
| Taste | Mild, firmer texture | Slightly sweeter, delicate |

Final Thoughts: Choosing the Right Option
Choosing between shrimp and prawns depends on personal preference, recipe requirements, and desired taste and texture. Understanding the differences in their anatomy, habitat, and culinary uses allows for more informed choices and creative experimentation in the kitchen.
Whether you are grilling tiger prawns or tossing shrimp into a quick stir-fry, each brings its unique qualities to the plate. Knowing these distinctions enhances your seafood selection and helps create flavorful, well-prepared dishes.
