5 Things to Consider When Determining a Crawfish’s Sex

Crawfish, famous for its feel-good yet straightforward taste, is one of the most popular delicacies in the world. Several restaurants have dedicated their menus to offering freshwater crustaceans to customers in Mesa alone. However, similar to other seafood, determining a crawfish’s sex is one of the things people get confused about. But how can you tell if a crawfish is male or female? Here are some tips.

1. Males Are Bigger

Male crawfish are more extensive than females. Their size is one of the easiest things to tell if you have a pair of crawfish in front of you. The males are about three inches in length and weigh approximately 1.5 ounces. If a crawfish is more extensive than this, it is more likely to be a male.

2. Females Have a Small Hole Behind Their Swimmerets

Although females are generally smaller in size, one of the signs you can use to tell if a crawfish is female is its small hole behind the swimmerets. If you try to look for it, you will be able to find a small spot that is only visible if you separate the hindmost part of the body from the head. The hole serves as the female’s reproductive opening.

3. Males Bear Bigger Claws

Although male crawfish are more significant, the most notable difference is in their claws. The males have enormous claws to protect their territory. The claws are also an indication of their health, often used as a defense against other males to establish their territory. You can also use the claw size of the crawfish to tell if it is male or female.

4. Females Have a Wider Abdomen

Females have a broader abdomen than males because of the fat deposits stored underneath their shells. The stomach can be as large as the body for some females. A broader abdomen is a sign it is carrying eggs. There is also a slight difference in color between males and females. Female crawfish are generally a little bit lighter in color.

5. Males Have a Fully-Developed Gonopod

Gonopods are found in both sexes but are more developed in males. A crawfish’s gonopods are tiny, appearing as a small pair of white threads. However, they grow as the male crawfish grows, reaching up to 4 inches in length. The gonopods are used for the male’s reproductive function.

Which Crawfish Sex is Better?

The two genders of crawfish are known for their different taste and size. Female crawfish are usually more undersized and more flavorful, tender, and juicy than males. Therefore, if you want to fish for a romantic dinner, choose female crawfish for it.

If you are looking for cheap and filling food, male crawfish are the best. Although males are smaller, the males are more flavorful and have thick shells. The males’ shells have a nice crunchy texture, which can accompany your chaser or be eaten on its own.


As compared to other kinds of seafood, it is easier to tell if a crawfish is male or female, particularly when you have a pair of crawfish in front of you. However, if you have just purchased crawfish from the market or grocery store, the task can be difficult. In that case, it’s best to ask the seller for the seafood’s gender to be sure.
