How To Distinguish Between Crayfish, Prawns, and Shrimp
When comparing their physiques, crayfish can be easily distinguished from prawns and shrimps because crayfish are bigger than prawns.
Even a child as young as six can tell the difference between the two. The only place it gets hard is with prawns and shrimps, as they have a very similar appearance.
Differentiating between crayfish, prawns, and shrimp can be challenging for many people, as these crustaceans share similarities in appearance.
However, there are key features that distinguish them from one another. Here are 40 detailed questions and answers to help you understand how to differentiate between crayfish, prawns, and shrimp:
Prawns, shrimps, and crayfish, and are all members of the crustacean family of aquatic animals. Despite their differences, they are sometimes confused because of their similar appearance. What distinguishes prawns, shrimps, and crawfish from one another, then?
We’ll explain all that in the paragraphs that follow.
Shrimp and Crayfish (What are Prawns): An Overview?
The term “prawn” refers to a wide variety of edible small aquatic crustaceans that have an exoskeleton and ten legs (members of the order decapods).
In the United Kingdom, Ireland, and Commonwealth countries, large swimming crustaceans or shrimp—especially those of commercial significance in the fishing industry—are referred to as prawns.
The name is less common in North America, where it usually refers to freshwater shrimp. The scientific status of the names shrimp and prawn is questionable. The terms have become nearly synonymous in modern usage as their meanings have evolved.
Shrimps
Shrimps are aquatic crustaceans that are characterized by long, slender, muscular abdomens and long antennae. Unlike crabs and lobsters, shrimp are found in saltwater and are often smaller than the other two crustaceans. They also have swimmerets, or pleopods, that are fully grown.
Shrimp and prawns may sound similar, but they are two different species. Shrimp have lamellar gills, which are side plates that cover portions of their bodies on the front and back, and they transport their eggs outside of their bodies under their tails.
This makes their distinctive slant more obvious, which is an additional quality to seek out when shopping for seafood.
Crayfish
Crayfish have an elongated first pair of claws that mimic lobster claws. The crayfish’s tail is the edible part since it has the most meat in it. Because of their tough exoskeleton to peel, crawfish are less popular than shrimp and prawns, even if other sections are edible.
It has no fishy scent and a very rich, almost buttery taste. They taste sweet as well. Because they live in freshwater, they have a characteristic expressive mineral odor that makes them much more recognizable.

Crawfish vs. crayfish
There is no difference between crawfish, crayfish, or crawdads. The phrase you use may vary greatly depending on where you live.
While Northerners are more likely to say crayfish, Louisianans are more likely to say crawfish. The phrase “crawdad” is widely used by people from the West Coast or Arkansas, Oklahoma, and Kansas.
Prawn Vs. Shrimp vs. Crawfish ~ Crayfish vs. Prawn vs. Shrimp
Even though they look a lot alike, crabs, shrimp, and crawfish are all different kinds of seafood. Despite their similarities, there are a few significant differences between them that are worth mentioning.
Appearance: Prawns and shrimp are very similar. They feature five pairs of legs, lengthy tails, and an exoskeleton, though not as robust as the crayfish’s. Prawns have three pairs of claws on their legs, but shrimp only have two pairs.
The best way to differentiate between shrimp and prawns is to look at their bodies. A crayfish can be best described as a little lobster. It has a robust exoskeleton, and claws, and is bigger than shrimp and prawns.
In comparison, shrimp are much more bent than prawns. All three are often tiny and eaten as part of a larger meal or as finger snacks. Though it wouldn’t be easy to tell them apart based just on size, prawns are frequently larger than shrimp.
Taste: In terms of taste, crayfish and shrimp differ from one another. The former has a somewhat sweeter, slightly saltier, and slightly mineral flavor. While prawns and shrimp taste very similar, prawns have a somewhat higher flesh content and sweetness.
Ecosystem: Crayfish mostly live in aquatic settings such as lakes, ponds, streams, and rivers. Still, some species of crawfish inhabit seawater.
They live in the shallow area of the water’s surface as well as the occasionally occurring ground holes along the water’s edge. To protect themselves from predators, they dig their tunnels and fill them with sand or mud.
Nutritional Value: Prawns are one of the best food sources of selenium, along with high quantities of copper, zinc, phosphorus, and magnesium.
However, shrimp are incredibly nutrient-dense meals since they include zinc, salt, potassium, magnesium, and phosphorus. Crayfish are rich in calcium, phosphorus, zinc, magnesium, iron, and B vitamins.
Uses: Prawns and shrimp are commonly served as finger snacks or in seafood drinks during cocktail parties. The most often consumed preparations of crawfish include crayfish pie, etouffee, and boil in Louisiana.
They are more often used as an ingredient in another dish than as crayfish on their own, even if they can occasionally be found in seafood cocktails with other shellfish.

Shrimp vs. prawn vs. lobster vs. crayfish
All crustaceans, including prawns, lobsters, shrimp, and crayfish, have segmented bodies, jointed legs, and a hard exoskeleton.
They are distinct species, though, and they usually inhabit separate environments. Some of their differences are listed below:
Prawns and shrimp are generally considered to have a stronger, brinier flavor; yet, lobster and crayfish can have a sweeter, more delicate texture.
The crayfish resembles smaller lobsters while lobsters are usually found in saltwater habitats.
The claws of a lobster are proportionately larger than their bodies, making them larger than crayfish.
Shrimps are smaller than lobsters and are frequently utilized as food and are usually found in marine habitats.
In size and form, prawns resemble shrimp, although they inhabit freshwater habitats. They serve as a source of food as well.
Difference between prawn and shrimp
Things can get tricky because prawns and shrimps look so similar to each other. If you ask, somehow they can tell the difference, they’ll tell you that one is bigger than the other. Some of their differences are listed below:
Both prawns and shrimps are ten-legged crustaceans. Still, their legs are a little different from each other. Shrimps only have one set of legs with claws on the end, whereas prawns have three pairs.
When comparing shrimp of the same size, prawns usually have proportionally larger legs.
Prawns are larger but shrimps have more varieties.
Similarities between shrimp and crayfish
Shrimps and crayfish both have two pairs of antennae, the longer of the two. They have five walking leg pairs, the first two or three of which contain claws. The first pair of claws on crayfish is expanded and resembles lobster claws.
The color of crayfish can also be used to distinguish them from shrimp.
Difference between crayfish and shrimp taste
Both marine animals have a thick texture and a subtle, non-fishy flavor. They’re a favorite among seafood enthusiasts because of their meatier texture. Because of how unique their flavors are from other seafood, crawfish, and shrimp are included in the same group.
The meat of shrimp is extremely fibrous but delicate, and it has a delicious, slightly salty flavor while the taste of crayfish is sweet with faint undertones of minerals.
In terms of taste, crayfish is similar to a mixture of lobster, shrimp, and crab. Therefore, even though crayfish and shrimp have a similar flavor profile, crayfish have a distinct flavor.
While shrimp are saltwater decapods with larger tails, crawfish are freshwater crustaceans. Despite their diminutive size, crawfish have a variety of tasty and edible body parts.
Similar to lobsters, crawfish have extremely soft meat that crumbles off their claws! Shrimp, on the other hand, lack large front claws. Their meat is also solid with a hint of chewiness.
Crawfish vs. shrimp allergy
Do shrimp and crawfish have the same allergy?
As crayfish are a kind of shellfish, an allergy to them suggests that other crustaceans are probably causing the problem. The seafood that falls under the category of crustaceans includes prawns, lobster, crab, barnacles, and krill.
The Bottom Line
Prawns, Shrimp, crawfish, and are renowned for their superior quality and nutrient content. They are also a delight for those who enjoy seafood.
Because they are sophisticated and elegant, shrimp and prawns are a great option for seafood cocktails at expensive gatherings.
Crayfish tastes great added to a seafood cocktail or simmered in a pot.
Declaring one to be superior to the other would be unfair to the other two, as each has merit and, in the right combinations, maybe a real delight.
FAQs
What is the difference between shrimp and crayfish?
The biggest differences between crawfish and shrimp are in their size, morphology, and type of water that they inhabit.
