Different Types of King Crab

Crab is a seafood delicacy that is enjoyed by people all over the world. From Alaskan king crab to Dungeness crab to snow crab, there are many different species of crab that offer unique flavors and textures. Here at Fog Harbor  we pride ourselves on serving the freshest and most delicious seafood in town. We are most well known as the best crab restaurant in San Francisco, and serve exclusively Dungeness crab. A crab species that has important ties to San Francisco history.

Today, however, we want to talk about a species of crab that we don’t serve at Fog Harbor, king crab (and other alaskan crabs). King crab is a delicacy that many people enjoy, but did you know that there are different types of king crab? In this article, we’ll explore the various types of king crab and explain the differences between them. Whether you’re a crab connoisseur or just a seafood lover, you’ll learn something new about these delicious crustaceans.

King crab from Alaska

When most people think of king crab, they think of the Alaskan king crab. Alaskan king crab is the largest of the three king crab species and can weigh up to 20 pounds. It has a rich, sweet flavor and a firm, flaky texture. 

Peradine Crab

Peradine crab, also known as red king crab, is another type of king crab that is highly sought after by seafood lovers. It is named after its reddish-brown shell, which is covered in spiny projections. This type of crab is slightly smaller than Alaskan king crab, with an average weight of 6-8 pounds. However, it is still considered a delicacy due to its sweet, delicate flavor and tender meat.

In addition to Alaskan and peradine crab, there is another type of king crab called the blue king crab. Blue king crab is the smallest of the three species, with an average weight of only 2-4 pounds. It is found in the Bering Sea and has a slightly sweeter flavor than Alaskan king crab.

Bairdi Crab vs King Crab

Now that we’ve covered the different types of king crab, let’s dive into some of the differences between them. One of the most common questions you might come across is about the difference between bairdi crab and king crab. Bairdi crab, also known as tanner crab, is often confused with king crab due to its similar appearance. However, bairdi crab is actually a separate species of crab. It has a slightly sweeter and more delicate flavor than king crab, but its meat is not as firm.

King Crab vs Opilio Crab

Another common question is about the difference between king crab and opilio crab. Opilio crab, also known as snow crab, is a smaller and less expensive alternative to king crab. While both types of crab have a sweet flavor, opilio crab has a milder taste and a more delicate texture than king crab. It is also easier to harvest, which makes it more affordable than king crab.

Types of Alaskan Crab

In addition to king crab and opilio crab, there are other types of Alaskan crab that are worth trying. One of these is the Dungeness crab, which is found in the waters off the coast of Alaska and the Pacific Northwest. Dungeness crab has a sweet, buttery flavor and a firm, flaky texture. It is often used in dishes like crab cakes and crab bisque.

Bairdi Crab vs Snow Crab

Another comparison worth making is between bairdi crab and snow crab. Snow crab is another type of crab that is often used as a substitute for king crab. It has a similar sweet flavor, but its meat is more delicate and less firm than king crab. Bairdi crab, on the other hand, has a sweeter flavor than snow crab but is not as firm.

Types of Snow Crab

Types of seafood

There are different types of snow crab as well, including the queen crab, which is found in the waters off the coast of Alaska and Russia. Queen crab has a sweet, delicate flavor and a flaky texture. It is often used in dishes like salads and pastas.

In the article we discuss everything from what each type of crab tastes like to the best ways to serve the different types of crab. You’re going to be glad you checked it out!

Opilio Crab vs Snow Crab

Finally, let’s talk about the difference between opilio crab and snow crab. While both types of crab are often used as a substitute for king crab, there are some differences in flavor and texture. Opilio crab has a milder, sweeter flavor than snow crab, but its meat is also more delicate. Snow crab, on the other hand, has a slightly sweeter flavor than opilio crab and a firmer texture. Both are absolutely delicious! 

Alaskan Crab Species

In addition to the types of crab we’ve discussed, there are several other species of crab found in the waters off the coast of Alaska. These include the golden king crab, the scarlet king crab, and the rock crab. Each of these species has a unique flavor and texture, making them worth trying if you’re a seafood lover. They are less common than some of the species that we’ve already discussed, but make sure to keep your eyes peeled for them either at your favorite seafood restaurants or your local fish market. 

King crab is a delicious and highly sought-after seafood that comes in different types and species. While Alaskan king crab is the most well-known type of king crab, peradine crab and blue king crab are also worth trying. And if you’re looking for an alternative to king crab, opilio crab and snow crab are both delicious options. 

We know that getting into all the different types of crab can be confusing, hopefully this article helped you break down the differences and similarities by these commonly found crabs. Still have questions? Feel free to write us and we’ll do our best to help answer them!
