Theres nothing quite like a seafood boil, in which you assemble a tasty selection of crustaceans and enjoy a hands-on affair. Such meals typically incorporate local components, making it easy to craft a large batch fit for a crowd. In the U.S., there are two famous cultural traditions that promote this culinary activity: the New England lobster feast and the Lousiana crawfish boil. Although they often incorporate similar ingredients, the different crustacean base used offers a distinct experience.
So, what is the difference between the two shelled and clawed aquatic creatures? Past their most immediately recognizable difference — size — there are actually a whole lot of disparities. Not only do the respective sea creatures lend themselves to a particular eating experience, but they each align with varying ingredients, too. Throw in different regions of habitation, and there are many culinary renditions of each animal. So, lets dive into the distinctions between these two crustaceans.
Lobster is an iconic seafood delicacy that encompasses many different species. The seagoing crustaceans are defined by certain characteristics: The creatures must live in saltwater and inhabit the ocean bottom. Most are greenish brown in life, though they dont all have large claws. Spiny lobsters, for example, only have tiny pinchers; hence, only the tails are eaten. Then, there are additional affiliations, such as langoustines, which may or may not be included under the conventional “lobster” moniker.
However, the most common association with the name is the Homarus americanus, colloquially referred to as the Maine lobster. This species is bright red when cooked and has the iconic sweet and juicy white flesh, which can be found in the claws, tail, and as smaller flavor-packed morsels throughout its legs. The animals larger size makes it a popular option for steaming, grilling, and boiling, and its meat can also be incorporated into iconic dishes like lobster rolls and bisque. This type of lobster is instantly recognizable and is an indispensable part of Americas culinary canon, especially in New England.
Crawfish, also referred to as crayfish, crawdads, and mudbugs, encompass a wide variety of crustacean species. Unlike their cousins, the lobsters, these creatures mainly live in freshwater and are much smaller in size — typically only three inches long. They inhabit small bodies of water, like streams and lakes, and hide underneath objects. Unlike the most popular lobster varieties, theyre found in multiple hues, with white, red, orange, and even blue varieties.
In flavor, many consider them to be even sweeter than lobster, with a naturally less salty quality due to their habitat. Plus, eating them is a fun and unique experience. Due to their smaller size, its necessary to put in work to get tiny bits of flesh out, with especially scrumptious bites found in the head. However, some clean the creatures and then integrate them into other dishes, like Cajun crawfish pies, salads, soups, and more. Due to their more affordable cost, these crustaceans are often incorporated into a wide variety of applications, although they do take more time to clean.
Are Lobster and Crayfish the Same Thing?
Lobster and crayfish are two types of crustaceans that look very similar at first glance. However they are not exactly the same. While they share some common traits there are several key differences between lobsters and crayfish.
In this article, we will explore the question – are lobster and crayfish the same thing? We will compare and contrast their taxonomy, anatomy, habitat, diet, and more By the end, you’ll have a clear understanding of how lobsters and crayfish are related but distinct creatures
Taxonomy – Different Families
Lobsters belong to the family Nephropidae while crayfish belong to one of three families: Cambaridae, Astacidae, or Parastacidae. So lobsters and crayfish are not classified in the same taxonomic family.
Lobsters are marine creatures while crayfish live in freshwater. The largest group of lobsters is the spiny lobsters, also known as rock lobsters. True lobsters have large front claws while spiny lobsters lack claws. There are many different species of crayfish including some quite large ones like the Tasmanian giant freshwater crayfish.
Anatomy – Similarities and Differences
Lobsters and crayfish have a number of anatomical similarities since they both belong to the order Decapoda (meaning 10 legs). They have elongated bodies, stalked eyes, antennae, a hard exoskeleton, and five pairs of legs including specialized claws on the first pair. They also both have long, muscular tails that propel them backward rapidly to escape predators.
However, there are also several key differences:
-
Lobsters have much larger front claws with one claw designed for crushing and the other for cutting. Crayfish have two smaller symmetrical claws.
-
Lobsters lack the spines found all over crayfish bodies and tails. Their tails are smooth.
-
Crayfish have a wider carapace (shell) than lobsters and it extends further down the body.
-
Lobsters have blunter rostrums compared to the pointed rostrums of crayfish.
So while they share the same basic body plan, lobsters and crayfish have distinct morphological differences.
Habitat and Geography
One of the biggest differences between lobsters and crayfish is their habitat:
-
Lobsters are exclusively saltwater creatures. They live at the bottom of oceans, seas, and coastal areas worldwide.
-
Crayfish live in freshwater lakes, rivers, streams, and ponds. Most crayfish are found in North America but there are species on every continent except Antarctica.
There are no crayfish species that can tolerate saltwater or marine lobsters that can live in freshwater. A crayfish transported to the ocean would quickly die just as a saltwater lobster released in a lake would perish. Their physiology is adapted to specific water conditions.
Diet and Feeding
Due to their large crushing claws, lobsters can easily open hard-shelled prey like clams, mussels, snails, crabs and even sea urchins. They also eat fish, shrimp, marine worms, and other small creatures. Lobsters are adept hunters and scavengers.
Without big claws, crayfish feed mostly on aquatic vegetation, detritus, insect larvae, worms, and mollusks. They may scavenge dead animals but do not actively hunt large prey. Their smaller claws are adapted for shoveling food particles into the mouth.
Behavior
Both lobsters and crayfish are generally nocturnal and solitary creatures that prefer to hide out during the day. They seek shelter in rocky dens, crevices, vegetation, or even dig holes in the substrate. Lobsters migrate seasonally in large groups but otherwise wander alone across seabeds looking for food and mates. Crayfish behave similarly in freshwater systems. Neither lobsters nor crayfish form permanent social groups.
Reproduction
Female lobsters and crayfish both carry eggs externally underneath their tails. The eggs are fertilized as they are laid and carried for several weeks or months before hundreds of tiny lobster or crayfish larvae hatch out. The larvae go through several planktonic stages as they grow before settling down on suitable bottom habitat.
Commercial Value
Lobsters and some crayfish are prized as premium seafood. Lobsters are especially expensive since they must be captured individually in traps. Rock lobster tails and lobster meat are particularly valuable. Large crayfish like the Australian red claw and North American crayfish are commercially harvested but not at the same level as true lobsters. Both are popular for home aquariums.
Conclusion
While lobsters and crayfish appear very similar, they belong to different families, live in different habitats, exhibit some key anatomical differences, have distinct diets and feeding behavior, and vary in commercial value. But they also share decapod traits and a preference for shelters and nocturnal activity.
Crawfish and lobsters hail from different regions
Crawfish and lobsters have both been consumed by humans for a long time. In the U.S., Native Americans foraged as part of their diet, both in the freshwaters of present-day Louisiana and along New Englands coastline. In the latter, lobsters lived ubiquitously and were utilized for fishing in addition to food. Due to their abundance, they quickly became integrated into local cuisine upon European arrival.
Although they didnt become a delicacy until the early 20th century, their more prominent regional status turned them into a widely consumed food. Conversely, crawfish remained relatively obscure until better transportation systems emerged in the 1960s. Today, most crawfish consumption remains in Louisiana, although theyre also enjoyed on the Atlantic coastline in smaller quantities.
Most lobsters are caught on the Atlantic coastline, with a small amount of spiny lobsters harvested in California. Internationally, crawfish are also featured in the cuisines of Nordic countries, as well as in Sichuanese Chinese cooking. Meanwhile, lobsters are consumed in coastal regions globally, including the Caribbean and Oceania, with spiny lobsters being popular in the Mediterranean, Asia, and Australia, too.
Crawfish and lobsters have varying culinary uses
Due to their varying sources, lobsters and crawfish have different culinary uses. When it comes to heating applications, steaming is a preferable choice for lobster; however, crawfish is solely boiled. Due to their voluminous tails, lobster meat can be served as an intact piece, as opposed to the smaller chunks of cleaned crawfish. As a result, crawfish is typically enjoyed whole or melded into dishes.
In Cajun cuisine, theyre frequently sautéed and featured in étouffée, a rich tomato-based stew with a bit of spice, or stuffed into bread. Meanwhile, in Italy, the meat is integrated into delicious pasta dishes. Lobsters also encompass a wide range of culinary uses. Past the iconic lobster roll, common combinations include pastas — especially macaroni and cheese — dips, soups, and, in the Caribbean, theyre typically grilled.
Since lobster tails are often frozen, theyre easier to integrate into cuisine further from harvesting areas, hence their frequent appearance in surf turf dinners. Regarding the meats flavor, the two creatures are similar. Some believe crawfish have a slightly sweeter palate, although it depends on the seafoods precise sourcing and preparation. Plus, theres a whole lot of variation in each species, which only adds to the flavor differences.

FAQ
Is a lobster the same as a crayfish?
Their external skeleton and segmented body classifies them into the group of crustaceans. Despite the fact they have very similar appearances, lobsters, rock lobsters and crayfish do not belong to the same family.
Do crawfish taste like lobsters?
In flavor, many consider them to be even sweeter than lobster, with a naturally less salty quality due to their habitat. Plus, eating them is a fun and unique experience.
Why do Australians call crayfish lobster?
Traditionally called crayfish by the locals, the name was changed ( in the face of some antagonism ) to Rock Lobster to market them first to the Japanese market and more recently to the Chinese. They are actually spiny lobsters and lack the large claws of the northern hemisphere true lobsters.
Is the crayfish’s eye similar to that of a lobster?
(4) The visual pigment of the crayfish thus has its maximum absorption displaced by 50 to 60 m~ towards the red end of the spectrum from that of the lobster and other marine crustacea. This shift parallels that found in both rod and cone pigments between fresh water and marine vertebrates.
Are crayfish and lobster the same?
Crayfish and lobster are both crustaceans that belong to order Decapoda. They are not the same, despite crayfish resembling small lobsters. People often confuse them due to their similar appearance. So, what is the difference between crayfish and lobster?
What is the difference between crawfish and lobster?
Crayfish and lobsters may look identical to the untrained eye. But each has characteristics that make it unique. Crayfish, also known as crawfish or crawdads, are part of the ‘small lobster’ invertebrate, arthropod family. They can reach a length of 6 inches, weigh about 8 lbs, and have a lifespan of 2 to 3 years.
What order do crayfish and lobster belong to?
Crayfish and lobster are both crustaceans that belong to order Decapoda. They are well known by people due to their taste as seafood. Crayfish resemble small lobsters hence commonly confused by people. So, what is the difference between crayfish and lobster?
Do crayfish have claws?
True lobsters and crayfish also differ from the reef lobsters (family Enoplometopidae) in having claws on the first three pairs of legs (one large pair of claws and two pairs of walking legs are tipped with small claws), rather than just one. Unlike true lobsters and crayfish, spiny (rocky) lobsters do not have large claws.
Are crayfish clawed lobsters?
Adding to the confusion is the fact that crayfish are closer in appearance and relation to clawed lobsters than the version without claws, and that there are many other names used for crayfish. These include crawdad, crayfish, crays and even mud bugs or mud puppies.
How do you know if a lobster is a crayfish?
If you’re buying, ask the person in charge. If it has uneven claws, is longer than 6 inches, and comes from saltwater, then it’s a lobster. If it has even claws, is on the shorter side, and comes from a freshwater habitat, then it’s a crayfish.
