Are Crawfish Bugs? No! But Why’re They Called So?

Do you want to know whether little crawfish are actually bugs? 

You must be in a fix if you should eat crawfish or not. Chances are, to you, they either resemble to bugs, or you’ve heard somebody calling them bugs.

Is it?

If yes, this well-researched blog post is for you.

Let’s uncover the truth behind this tasty shellfish.

First Things First, Let’s Know What is Crawfish.

Crawfish, also known as crayfish or crawdads, belong to a group of animals called crustaceansCrustaceans are a large and diverse group of arthropods that include crabs, lobsters, shrimp, krill, and barnacles. 

They’re characterized by a hard exoskeleton, jointed appendages, and a segmented body. Crustaceans are found in all aquatic environments, from freshwater to saltwater, and some species even live on land.

Now, Let’s Break Crawfish Down Even Further. 

Bugs, scientifically speaking, belong to a group called insects. Think of ants, bees, beetles, and butterflies. Bugs have six legs, a three-part body, and usually wings. They breathe through tracheae instead of lungs or gills.

Crawfish, on the other hand, belong to a different group known as decapods. They have a hard exoskeleton, jointed limbs, and breathe through gills.

You might wonder why people sometimes refer to crawfish as bugs. Well, it’s all about regional slang and local lingo. 

In some areas, people use the word “bug” as a catch-all term for any small creepy-crawly creature. It’s sort of a colloquial way to group them together, even though they’re not technically bugs in the scientific sense.

Why Are Crawfish Technically or Scientifically Seafood?

All types of crawfish are technically seafood because they’re crustaceans, a type of aquatic animal. The term “seafood” refers to any edible aquatic animal, whether it is from the sea, freshwater, or even an inland lake. 

So, even though crawfish are mostly found in freshwater, they’re still considered seafood.

Here are some other reasons why crawfish are considered seafood:

  • They’re closely related to other crustaceans commonly eaten as seafood, such as lobsters, shrimp, and crabs.
  • They have a similar flavor and texture to other seafood, making them a popular choice for seafood dishes.

So, Here’s the Exciting Part!

Crawfish are an absolute delight to eat, no matter if you get them from water or swamp! They’re incredibly popular in Southern cuisine, especially in places like Louisiana, where they’re a true culinary tradition. 

So, when you’re savoring those tasty crawfish boils or enjoying a flavorful étouffée, remember that you’re indulging in the delectable world of crustaceans, not bugs!

To Sum it up

While crawfish may be called “bugs” by some folks, they’re not insects or bugs like beetles or ants. These little fellas are crustaceans, a unique and delicious type of shellfish. So, the next time you find yourself enjoying a plate of succulent crawfish, you can be sure that you and your dear ones are eating seafood, not bugs.


Why is terrestrial crayfish (red swamp crayfish) not a bug?

Commonly eaten red swamp crayfish is among one of the crawfish species that can live on land. These species are known as terrestrial crayfish.

Terrestrial crayfish are adapted to living on land, and they have a number of features that help them survive in this environment—yet owing to their classification as decapods, red swamp crayfish are not considered bugs but crustaceans. Hence, they’re seafood.

Are crawfish related to roaches?

Crawfish, crayfish, or crawdads are not closely related to roaches. Both crawfish and roaches are arthropods and belong to the phylum Arthropoda. Yet, they belong to different classes. 

Crawfish are crustaceans, belonging to the class Malacostraca, which includes crabs, lobsters, and shrimp. These animals breathe through gills. 

Roaches, on the other hand, are insects and belong to the class Insecta. They breathe through spiracles (trachea).

Crawfish are typically found in freshwater habitats like streams, rivers, and lakes. In contrast, roaches are commonly found in a variety of environments, including both indoor and outdoor settings. 

Thus, both have different anatomical features, behaviors, and ecological roles. So, they’re not closely related.

Can crawfish be poisonous?

Crawfish are not poisonous, but they can be if they have ingested toxic chemicals or algae. This is more likely to happen if the crawfish are harvested from polluted water. The toxins can cause a variety of health problems, including nausea, vomiting, diarrhea, and even death. So, be careful to get crawfish from trusted sources only.
