Lobsters vs Crayfish: Taste, Price, Size, Difference, Australia

Lobsters and crayfish are fascinating crustaceans that have intrigued and delighted seafood enthusiasts worldwide. While they share similarities, numerous distinctions set them apart, influencing their taste, price, and cultural significance. This article delves deep into the various species of lobster, compares the taste and price of crayfish and lobster, and explores their roles in different regions, particularly in Australia. Additionally, we will discuss the differences and similarities between crayfish, lobster, and crawfish, and examine their sizes.

Understanding Crayfish and Lobsters


Crayfish, also known as crawfish or crawdads, are freshwater crustaceans that resemble small lobsters. They are primarily found in freshwater bodies such as rivers, lakes, and streams. There are over 600 species of crayfish, with a significant number inhabiting North America. Crayfish play a crucial role in their ecosystems, acting as both predators and prey.


Lobsters are larger marine crustaceans found in oceans around the world. They belong to the family Nephropidae or Homaridae. Lobsters are known for their strong claws, which they use for defense and capturing prey. There are different species of lobster, including the American lobster (Homarus americanus) and the European lobster (Homarus gammarus). Lobsters are highly prized for their succulent meat and are considered a luxury food item.

Crayfish vs Lobster: Key Differences


One of the primary differences between crayfish and lobsters is their habitat. Crayfish live in freshwater environments, while lobsters are found in saltwater, particularly in the Atlantic Ocean and the Mediterranean Sea.

Physical Appearance

While crayfish and lobsters look similar, there are noticeable differences in their size and features. Lobsters are generally much larger, with the biggest lobsters weighing up to 44 pounds. Crayfish, on the other hand, are smaller, typically ranging from 3 to 6 inches in length.


The taste of crayfish vs lobster is another distinguishing factor. Lobster meat is known for its rich, sweet flavor and tender texture, making it a popular choice for gourmet dishes. Crayfish, while also tasty, have a slightly milder flavor and a firmer texture. The subtle differences in taste can influence the choice of seafood for various recipes.

Crayfish vs Lobster in Different Regions

Crayfish vs Lobster Australia

In Australia, both crayfish and lobsters are highly regarded. The Tasmanian crayfish, also known as the Tasmanian giant freshwater crayfish (Astacopsis gouldi), is one of the largest freshwater invertebrates in the world. This species can grow up to 6 kilograms and is found in Tasmania's rivers and streams. Australian lobsters, particularly the Southern Rock Lobster (Jasus edwardsii), are also famous for their exquisite taste and are a staple in the Australian seafood market. When considering crayfish vs lobster Australia, both options offer unique flavors and culinary experiences that reflect the country's rich marine biodiversity.

Tasmanian Crayfish vs Lobster

Comparing Tasmanian crayfish vs lobster reveals interesting insights. The Tasmanian crayfish is a freshwater species, while the Southern Rock Lobster is a marine species. Both are highly valued, but their habitats, sizes, and culinary uses differ. The Southern Rock Lobster is often served in high-end restaurants, whereas Tasmanian crayfish are more commonly found in local markets and used in traditional dishes. The comparison of Tasmanian crayfish vs lobster highlights the diversity within Australian seafood offerings.

Different Species of Lobster

Lobsters are diverse creatures found in oceans worldwide. They belong to the family Nephropidae and are primarily divided into two types: clawed lobsters and spiny lobsters.

  1. Clawed Lobsters

    • American Lobster (Homarus americanus): This is the most well-known species, primarily found on the Atlantic coast of North America. It is renowned for its large claws and sweet, tender meat.
    • European Lobster (Homarus gammarus): Similar to the American lobster but found in the eastern Atlantic Ocean. It has a slightly different color and a distinct taste.
  2. Spiny Lobsters

    • Caribbean Spiny Lobster (Panulirus argus): Found in the warmer waters of the Caribbean and the Gulf of Mexico, this species lacks large claws but compensates with long, spiny antennae.
    • California Spiny Lobster (Panulirus interruptus): Located along the Pacific coast of North America, this species is highly valued for its delicious tail meat.
    • Australian Spiny Lobster (Jasus edwardsii): Commonly known as the Southern Rock Lobster, it is found in the waters off southern Australia and New Zealand and is prized for its sweet, succulent meat.

Crayfish vs Lobster Taste

The taste of crayfish and lobster, though similar, has subtle differences that connoisseurs can distinguish.

  1. Lobster Taste

    • Lobsters, especially the American and European varieties, are known for their rich, sweet flavor. The meat is tender, succulent, and slightly briny, offering a luxurious taste experience. The tail meat is firm and dense, while the claw meat is softer and more delicate.
  2. Crayfish Taste

    • Crayfish, also known as crawfish in some regions, have a milder, more subtle flavor compared to lobsters. They are often described as having a slightly sweet and nutty taste, with a texture that is less firm than lobster meat. The taste of crayfish can vary depending on their habitat and diet, with those from cleaner waters generally offering a better flavor profile.

Crayfish vs Lobster Price

The price of crayfish and lobster can vary significantly based on factors such as species, size, and region.

  1. Lobster Price

    • Lobsters are generally more expensive than crayfish. The American lobster, due to its popularity and demand, commands a high price, especially during peak seasons. European lobsters are also costly, often even more so than their American counterparts. Spiny lobsters, especially those from Australia and California, are prized and can fetch premium prices in markets worldwide.
  2. Crayfish Price

    • Crayfish are typically more affordable than lobsters. In regions where they are abundant, such as the southern United States and Australia, crayfish are considered a more economical seafood option. Prices can vary, however, with larger, high-quality crayfish fetching higher prices.

Crayfish vs Lobster Australia

Australia is home to a variety of both lobsters and crayfish, each with its unique characteristics and market demand.

  1. Australian Lobsters

    • The Southern Rock Lobster (Jasus edwardsii) is highly sought after in both domestic and international markets for its sweet, delicate flavor and firm texture. It is a significant export product, particularly to Asian markets.
    • The Eastern Rock Lobster (Sagmariasus verreauxi) is another important species, valued for its large size and high-quality meat.
  2. Australian Crayfish

    • In Australia, the term "crayfish" often refers to what other regions might call lobsters, particularly spiny lobsters. The Red Claw Crayfish (Cherax quadricarinatus) is a native freshwater species that is farmed extensively. It is appreciated for its mild flavor and tender meat, making it a popular choice for both local consumption and export.

Crayfish vs Lobster vs Crawfish

The terminology around crayfish, lobster, and crawfish can be confusing, as these names are used differently across various regions.

  1. Crayfish

    • Crayfish are freshwater crustaceans found in rivers, lakes, and streams. They are smaller than lobsters and are known by different names in different parts of the world. In Australia and New Zealand, the term "crayfish" often refers to spiny lobsters.
  2. Lobster

    • Lobsters are primarily marine crustaceans, with clawed lobsters found in colder waters and spiny lobsters in warmer seas. They are generally larger than crayfish and have a more robust flavor profile.
  3. Crawfish

    • Crawfish is another term for crayfish, commonly used in the southern United States. They are celebrated in Cajun and Creole cuisine, especially in Louisiana, where they are a staple in dishes like crawfish boils and étouffée.

Crayfish vs Lobster Size

Size is one of the most noticeable differences between crayfish and lobster.

  1. Lobster Size

    • Lobsters can grow to impressive sizes, with the American lobster being one of the largest crustaceans. They can weigh over 40 pounds, although commercially caught lobsters are usually much smaller, averaging between 1 to 3 pounds. The spiny lobsters are also sizable, with some species reaching weights of up to 15 pounds.
  2. Crayfish Size

    • Crayfish are significantly smaller than lobsters. Most crayfish species grow to about 3 to 6 inches in length and weigh only a few ounces. The largest species, such as the Tasmanian Giant Freshwater Crayfish (Astacopsis gouldi), can reach up to 6 kilograms (13 pounds), but this is an exception rather than the norm.


In summary, lobsters and crayfish, while sharing some similarities, exhibit distinct differences in species, taste, price, and size. Lobsters, especially the clawed and spiny varieties, are larger, more expensive, and have a richer flavor compared to the more affordable, milder-tasting crayfish. The terminology used to describe these crustaceans varies by region, adding to the complexity of their classification. In Australia, both lobsters and crayfish hold significant culinary and economic value, with unique species contributing to the diversity of seafood available. Understanding these differences enhances our appreciation of these remarkable creatures and their roles in global cuisine.
