No matter where you live, you’ve probably heard people talk about crawfish, crayfish, and crawdads. It’s common to wonder what the difference is between crawfish vs. crayfish. Believe it or not, there is no difference at all. The words “crawfish” and “crayfish” refer to the same animal. They have so many different names because of regional differences in language, but people are referring to the same creature regardless of the name used. Keep reading to find out why these creatures have so many different names.
What Is a Crawfish?

Before we dive into naming conventions, let’s talk about what these creatures are. Crawfish are small, freshwater crustaceans. Crawfish are small, freshwater crustaceans. They look like miniature lobsters, with a pronounced pair of strong, pinching claws, a tough carapace, and a broad, flat tail. Most crawfish are deep blue or red, but certain species can appear greenish-black or brown as well.
These little crustaceans are considered a delicacy just about anywhere in the world. They feature in a variety of seafood dishes, and in places like Louisiana and other states in the Deep South, they’re an essential part of authentic seafood gumbo and other regional cuisine. Crawfish have a distinct, meaty taste that differs from the more delicate flavor of lobster. The meat is usually described as sweet, and crawfish give off a strong aroma when cooked.

These little crustaceans have so many names that it’s no wonder people think they are referring to more than one animal species. Plus, there are over 600 species of crawfish worldwide. Most crawfish eaten in the U.S. are either the red swamp crawfish (Procambarus clarkii) or the white river crawfish (Procambarus zonangulus).
Depending on where you live in the U.S., you might hear these creatures called:
- Crawfish
- Crayfish
- Crawdads
- Crawdaddies
- Mudbugs
What you call these animals essentially comes down to where you grew up. Northerners usually call them “crayfish.” People from the West Coast and parts of the Midwest call them “crawdads,” and Southerners typically call them “crawfish.” You may also hear “crawdaddies” or “mudbugs” in the Deep South. If you want to get technical, “crayfish” is the accepted term for the crustacean in standard American English. However, when you’re cooking or dining, “crawfish” is the more widely used term.
Crawfish in Other Countries

There are also freshwater crawfish similar to those in the U.S. that are consumed in Australia. Crustaceans of the most common species of crawfish, Cherax destructor, are called “yabbies.” However, several other species are popular in different regions, such as the Koonac, Gilgie, Marron, and Redclaw species.
Unfortunately, that’s not where the confusion ends. People in other English-speaking countries also use the words “crayfish” and “crawfish.” However, in this case, they are not referring to the same crustacean eaten in the U.S. In South Africa, Australia, and New Zealand, “crayfish” or “crawfish” can also refer to spiny lobster or rock lobster, which are saltwater species of lobster in the genus Jasus that lack large front claws. So, the word “crayfish” is used for saltwater species, while “yabby” is used for freshwater species.
Crawfish Habitats

Crawfish can be found just about anywhere that has shallow, slow-moving freshwater. This includes lakes, streams, ponds, swamps, and rivers. However, some species can also tolerate brackish water.Of over 600 species, more than 400 live in North America and over 100 live in Australia. However, they can be found all over the world except for the continents of mainland Africa and Antarctica. This means that these little creatures are pretty easy to find no matter where you live.
If you ever spent time playing in a creek as a child, you likely saw some of these creatures at some point. Most crawfish dig burrows in the mud for shelter, creating underground tunnels. They also like to hide under rocks, so if you go looking for them, find some shallow water and start turning over rocks. You are bound to find some.
