The world of seafood can be a confusing place, especially when it comes to the terms “prawns” and “shrimps.” Many people use these words interchangeably, but are they really the same thing? In this article, we’ll delve into the world of crustaceans and explore the differences between prawns and shrimps.
What are Prawns and Shrimps?
Before we dive into the differences, let’s first define what prawns and shrimps are. Both prawns and shrimps belong to the order Decapoda, which also includes crabs, lobsters, and crayfish. They are both types of crustaceans, characterized by their hard exoskeletons, multiple limbs, and segmented bodies.
Biological Classification
From a biological perspective, prawns and shrimps are both classified as follows:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Malacostraca
- Order: Decapoda
However, this is where the similarities end. Prawns and shrimps belong to different suborders and families.
Prawns
Prawns belong to the suborder Caridea and are part of the family Palaemonidae. They are typically found in freshwater and brackish environments, although some species can be found in saltwater.
Shrimps
Shrimps, on the other hand, belong to the suborder Natantia and are part of the family Penaeidae. They are typically found in saltwater environments, although some species can be found in freshwater.
Differences in Appearance
One of the main differences between prawns and shrimps is their appearance. Prawns tend to be larger than shrimps, with some species reaching lengths of over 30 cm (12 in). Shrimps, on the other hand, are generally smaller, with most species reaching lengths of around 10-15 cm (4-6 in).
Another difference is the shape of their bodies. Prawns have a more elongated body shape, with a longer tail and larger claws. Shrimps have a more compact body shape, with a shorter tail and smaller claws.
Claws
One of the most distinctive features of prawns and shrimps is their claws. Prawns have larger, more powerful claws than shrimps, which they use for defense and capturing prey. Shrimps, on the other hand, have smaller claws that are more suited for grasping and manipulating food.
Differences in Habitat and Distribution
Prawns and shrimps also differ in their habitat and distribution. Prawns are typically found in freshwater and brackish environments, such as rivers, lakes, and estuaries. Shrimps, on the other hand, are typically found in saltwater environments, such as oceans and seas.
Geographical Distribution
Prawns are found in tropical and subtropical regions around the world, including Asia, Africa, and the Americas. Shrimps are also found in tropical and subtropical regions, but are more widely distributed, with species found in every ocean and sea.
Differences in Behavior and Diet
Prawns and shrimps also differ in their behavior and diet. Prawns are generally more solitary animals, only coming together to mate. Shrimps, on the other hand, are often found in large schools, and are known for their complex social behavior.
Diet
Prawns are opportunistic feeders, eating a wide range of plants and animals, including algae, plankton, and small invertebrates. Shrimps are also opportunistic feeders, but tend to eat more small invertebrates, such as plankton and brine shrimp.
Culinary Differences
Finally, prawns and shrimps differ in their culinary uses. Prawns are often used in Asian cuisine, where they are prized for their sweet flavor and firm texture. Shrimps, on the other hand, are often used in Western cuisine, where they are prized for their mild flavor and versatility.
Cooking Methods
Prawns are often cooked using high-heat methods, such as stir-frying and grilling. Shrimps, on the other hand, are often cooked using lower-heat methods, such as boiling and steaming.
Conclusion
In conclusion, while prawns and shrimps are both types of crustaceans, they are not the same thing. They differ in their biological classification, appearance, habitat and distribution, behavior and diet, and culinary uses. Whether you’re a seafood enthusiast or just a curious cook, understanding the differences between prawns and shrimps can help you appreciate these delicious crustaceans even more.
| Characteristics | Prawns | Shrimps |

What is the difference between prawns and shrimps?
The primary difference between prawns and shrimps lies in their biological classification. Prawns belong to the suborder Dendrobranchiata, while shrimps belong to the suborder Pleocyemata. This classification difference affects their physical characteristics, such as the structure of their shell and the number of claws.
Another key difference is their habitat and geographical distribution. Prawns are generally found in freshwater environments, such as rivers and lakes, while shrimps are commonly found in saltwater environments, such as oceans and seas. However, some species of prawns can be found in brackish water, which is a mixture of fresh and saltwater.
Are prawns and shrimps interchangeable terms?
In some regions, particularly in the United States, the terms “prawns” and “shrimps” are often used interchangeably. However, in other parts of the world, such as the United Kingdom and Australia, “prawns” is the preferred term for both freshwater and saltwater species.
Despite the interchangeable usage, it’s essential to note that the terms “prawns” and “shrimps” have distinct meanings in the context of culinary and scientific applications. Using the correct term can help avoid confusion and ensure accurate communication.
What are the physical characteristics of prawns and shrimps?
Prawns and shrimps have distinct physical characteristics that set them apart. Prawns tend to have a longer shell and a more elongated body shape than shrimps. They also have three pairs of claw-like legs, whereas shrimps have two pairs. Additionally, prawns have a more prominent rostrum, which is the pointed structure at the front of their shell.
Shrimps, on the other hand, have a more compact body shape and a shorter shell than prawns. They also have a less prominent rostrum and a different arrangement of their legs and claws. These physical differences can help identify whether a species is a prawn or a shrimp.
Which is larger, prawns or shrimps?
Prawns tend to be larger than shrimps. Some species of prawns can grow up to 12 inches in length, while shrimps typically reach a maximum length of around 2-3 inches. However, there are some species of shrimps that can grow larger than prawns, such as the Japanese tiger prawn, which can reach lengths of up to 8 inches.
It’s essential to note that size can vary greatly depending on the species and environmental factors. Both prawns and shrimps can range in size from small to large, and size alone is not a reliable indicator of whether a species is a prawn or a shrimp.
Are prawns and shrimps edible?
Yes, both prawns and shrimps are edible and are a popular ingredient in many cuisines around the world. They are a good source of protein and are often used in a variety of dishes, such as stir-fries, curries, and seafood paella.
Prawns and shrimps have a similar flavor profile, but prawns tend to have a sweeter and more delicate taste than shrimps. Shrimps, on the other hand, have a more robust flavor and a firmer texture than prawns. Both prawns and shrimps can be cooked in a variety of ways, including boiling, steaming, and sautéing.
Can prawns and shrimps be farmed?
Yes, both prawns and shrimps can be farmed. Prawn farming is a significant industry in many countries, particularly in Asia, where prawns are widely cultivated for both domestic consumption and export. Shrimp farming is also a major industry, with many countries around the world cultivating shrimps for both food and ornamental purposes.
Prawn and shrimp farming can be done using a variety of methods, including intensive and extensive systems. Intensive systems involve high-density stocking and the use of feed and other inputs, while extensive systems involve lower-density stocking and more natural conditions. Both prawns and shrimps can be farmed sustainably, but it’s essential to ensure that farming practices do not harm the environment or local ecosystems.
