What are the biological differences between prawns and shrimps?
The primary distinction between prawns and shrimps lies in their biological classification. Both belong to the crustacean family, but they fall under different suborders. Prawns are part of the Dendrobranchiata suborder, while shrimps belong to the Pleocyemata suborder. This difference in suborders leads to variations in their physical anatomy, reproductive methods, and behavior.
One key biological difference is in their gill structures. Prawns have branching gills, whereas shrimps have lamellar or plate-like gills. Additionally, prawns have three pairs of claw-like legs, while shrimps typically have only two. These distinctions, though subtle, are significant for scientists and marine biologists studying these species.
Another notable difference is in their reproductive methods. Prawns release their eggs into the water, allowing them to float freely, while shrimp eggs are carried by the mother until they hatch. This impacts their population dynamics and survival rates in the wild.
Physical characteristics: How can you tell them apart?
What are the key physical differences?
At first glance, prawns and shrimps might look nearly identical, but there are physical traits that set them apart. One of the easiest ways to differentiate them is by examining their body structure. Prawns usually have straighter bodies with longer legs, while shrimps have a noticeable curve in their bodies and shorter legs.
Another distinguishing feature is their size. In general, prawns are larger than shrimps, although this is not a hard-and-fast rule, as size can vary depending on the species. The rostrum, or the beak-like extension on their heads, also differs between the two. Prawns typically have a longer and more prominent rostrum compared to shrimps.
What about their shells and tails?
Shell texture can also be a differentiating factor. Prawns often have softer shells, making them easier to peel, whereas shrimps tend to have harder, more rigid shells. Additionally, the coloration of their tails may vary, with prawns generally appearing brighter and more vibrant.

Where do prawns and shrimps live?
The habitats of prawns and shrimps are another key difference. Prawns are predominantly found in freshwater environments like rivers and lakes, although some species also inhabit brackish or saltwater. Shrimps, on the other hand, are more commonly found in saltwater, particularly in oceans and seas.
Geographically, prawns are more prevalent in tropical and subtropical regions, whereas shrimps can be found worldwide, from shallow coastal waters to deep-sea environments. These habitat preferences influence their availability and price in various markets.
How are prawns and shrimps caught or farmed?
Both prawns and shrimps are harvested through a combination of wild fishing and aquaculture. Wild-caught prawns are often captured using traps or nets, while shrimp fishing typically involves trawling. However, trawling has been criticized for its environmental impact, as it can damage ocean floors and result in bycatch.
In terms of aquaculture, prawns are often farmed in freshwater ponds, whereas shrimps are raised in saltwater environments. Farming practices for both species have improved over the years, with greater emphasis on sustainability and reducing environmental impact.
Culinary uses: Do prawns and shrimps taste different?
One of the most debated aspects of prawns vs shrimps is their flavor. While both are delicious and versatile, prawns are often described as having a sweeter, more delicate taste, whereas shrimps have a stronger, more pronounced flavor. This difference in taste makes them suitable for different types of dishes.
For example, prawns are often used in high-end dishes like seafood pasta or grilled skewers, where their sweetness can shine. Shrimps, on the other hand, are a staple in comfort foods like shrimp cocktails, fried rice, and gumbo. Both prawns and shrimps can be grilled, boiled, steamed, or fried, depending on the recipe.
How should you cook prawns vs shrimps?
Cooking methods for prawns and shrimps are largely interchangeable, but their size and texture may influence the cooking time. Prawns, being larger, often require a slightly longer cooking time, whereas shrimps cook very quickly and are prone to becoming rubbery if overcooked.
- Grilling: Prawns are ideal for grilling due to their larger size and firmer texture.
- Boiling: Shrimps can be boiled quickly and are perfect for shrimp cocktails or salads.
- Stir-frying: Both prawns and shrimps work well in stir-fry dishes, but prawns add a touch of elegance.
Are prawns or shrimps healthier?
Both prawns and shrimps are excellent sources of protein, vitamins, and minerals, but there are slight nutritional differences. Prawns tend to have higher calorie and fat content due to their larger size, while shrimps are lower in calories and fat but still rich in nutrients like omega-3 fatty acids, vitamin B12, and selenium.
Both are low in carbohydrates and make excellent choices for low-carb or ketogenic diets. However, people with high cholesterol should consume them in moderation, as both are relatively high in dietary cholesterol.
FAQs: Common questions about prawns vs shrimps
