Is a crayfish a crustacean?
Crayfish are freshwater crustaceans resembling small lobsters (to which they are related). They are also known as crawfish, crawdads, freshwater lobsters, mountain lobsters, mudbugs, or yabbies. Taxonomically, they are members of the superfamilies Astacoidea and Parastacoidea. They breathe through feather-like gills.
Where do crayfish live?
The crayfish usually live not only in cool clear waters of fast currents, but also in more temperate waters, with slimy bottom, and of less current However, the middle and lower water courses, the river basins, and the headwaters of rivers and streams can also be inhabited by these crabs.
How many types of crayfish are there?
There are three families of crayfish, two in the Northern Hemisphere and one in the Southern Hemisphere. The Southern Hemisphere (Gondwana-distributed) family Parastacidae lives in South America, Madagascar and Australasia, and is distinguished by the lack of the first pair of pleopods.
Are crayfish edible?
In several countries, particularly in Europe, native species of crayfish are under threat by imported variants, particularly the signal crayfish ( Pacifastacus leniusculus) Crayfish are eaten worldwide. Like other edible crustaceans, only a small portion of the body of a crayfish is eaten.
Is a crawfish a crab?
Many people think that crawfish meat should taste like a lobster or crab because it is a crustacean, but crawfish is actually classified as a type of fish.
Are crawfish and crabs the same?
Compared to crab, crawfish do have a stronger flavor and are usually much meatier. Many people describe the flavor of crawfish as a combination of shrimp and crab, as they are slightly salty, a little sweet, and have a bit of mineral flavor.

Appearance. If you placed a Maine lobster next to a crawfish, the only major difference most people would notice is the size. In fact, crawfish really do look like baby lobsters. Crawfish average in size from two to six inches in length, while lobster can grow to more than twenty inches.
Is crawfish a shrimp?
The main difference between crawfish and shrimp is that the crawfish is an exclusively freshwater decapod with a pair of large, front claws whereas the shrimp is usually a saltwater decapod with a long tail. Furthermore, shrimps are larger than crawfish.
Are crawfish and crayfish the same?
Crawfish, crayfish, and crawdads are the same animal. Which term you use may depend much on where you live. Louisianans most often say crawfish, whereas Northerners are more likely to say crayfish. People from the West Coast or Arkansas, Oklahoma, and Kansas often use the term crawdad.

Terminology
The name "crayfish" comes from the Old French word escrevisse ( Modern French écrevisse ). The word has been modified to "crayfish" by association with "fish" ( folk etymology ). The largely American variant "crawfish" is similarly derived.
Anatomy
The body of a decapod crustacean, such as a crab, lobster, or prawn (shrimp), is made up of twenty body segments grouped into two main body parts, the cephalothorax and the abdomen. Each segment may possess one pair of appendages, although in various groups, these may be reduced or missing. On average, crayfish grow to 17.5 cm (6.9 in) in length.
Fossil record
Fossil records of crayfish older than 30 million years are rare, but fossilised burrows have been found from strata as old as the late Palaeozoic or early Mesozoic.
Threats to crayfish
Crayfish are susceptible to infections such as crayfish plague and to environmental stressors including acidification. In Europe, they are particularly threatened by crayfish plague, which is caused by the North American water mold Aphanomyces astaci. This water mold was transmitted to Europe when North American species of crayfish were introduced.
Invasive pest
In several countries, particularly in Europe, native species of crayfish are under threat by imported variants, particularly the signal crayfish ( Pacifastacus leniusculus)
Uses
Crayfish are eaten worldwide. Like other edible crustaceans, only a small portion of the body of a crayfish is eaten. In most prepared dishes, such as soups, bisques and étouffées, only the tail portion is served.
Crabs
Crabs are known for their distinctive short tails and rounder bodies alongside some rather impressive claws. These creatures come in a variety of forms ranging from hermit crabs to full-scale crabs of more intimidating varieties.
Lobsters
Lobsters are not an animal that people generally consider to be pets, but there are actually quite a bit of aquatic enthusiasts who find that these creatures are great at adding a little something extra to the right tank. In fact, lobsters can make for an exciting addition to your tank if you know how to manage them.
Crayfish
Crayfish are creatures that are known for their distinctive relation to lobsters. Most people who are unfamiliar with these tiny beasts confuse them for smaller lobsters, and while it is an understandable point of confusion, they are actually entirely separate creatures.
Dwarf Shrimp
If there is one creature that looks great in a variety of tanks, the dwarf shrimp takes the cake. These small creatures are great at scurrying around and looking busy for all the world to see.
Conclusion
Though these four kinds of creatures are all crustaceans, they are all quite different in appearance and temperament. This is what makes it so important to avoid generalizations that could result in problems down the line.
ABOUT ME
Hi everyone! I’m Michael and this is the place where I nerd out about shrimp. So, if you are interested in getting into this hobby or just want some extra tips and tricks, well this is the right place for you. On this blog, I share all the things I learn about shrimp breeding as I go.

Definition
Crawfish (or crayfish), lobsters, crabs, and shrimp are Crustaceans, which come from the arthropod classification, which are invertebrates that have an exoskeleton, a segmented body, and paired jointed appendages (like bugs). Other crustaceans are prawns, krill, woodlice, and barnacles.
Pros
If you have a busy life, owning a pet may be very overwhelming. Therefore, you need ones that assert their presence without taking too much out of you, crayfish are perfect.
Cons
Generally, crayfish species do not exhibit social behavior. In crayfish, ‘social phases’ are usually restricted to interactions during mating and the maternal care of offspring.
Selecting the Right Pet Crayfish
Before you adopt a pet crayfish, you need to find out about its behavior, feeding preferences, and care requirements. That way, you would be acquainted with the do’s and don’ts as well as how to properly handle and take care of it.
In Conclusion
Of course, there are no pets that are for everyone. Nonetheless, despite the Cons, I still believe that having crayfish as pets is far more rewarding than it is detrimental.

Main Characteristics of The Crayfish
What Is The Crayfish´S Size
- These crustaceans are usually only seventeen centimeters long and like the rest of the arthropods,they also molt their exoskeleton. Since they are decapods, they have five pairs of legs inserted on their belly, where the first of them correspond to two well-developed pincerswhich they employ to capture and manipulate their food. The next legs are also tweezers, but much sm…
Crayfish´S Anatomic Features
- As we mentioned earlier, the body of these creatures is divided into several parts that we will describe below. Abdomen:lower part of the body of the crab Antenna: organ of perception of the crab Antennule:small antenna. Mouth:tip of the largest legs of the crayfish. Head:top of the crayfish. Cheliped:anterior leg terminated by a mouth. Endophyte:inner part of the uropod. Exoph…
Crayfish´S Common Habitats
- The crayfish usually live not only in cool clear waters of fast currents, but also in more temperate waters, with slimy bottom, and of less current However, the middle and lower water courses, the river basins, and the headwaters of rivers and streams can also be inhabited by these crabs. In general, these crustaceans prefer to live in shallow rivers plenty of vegetation. It is essential for t…
Crayfish´S Distribution
- These crabs are distributed throughout the world, with the sole exception of the African continent. Of the five hundred species that exist in the world, only five of them are autochthonous of Europe. For this reason, this small crustacean is distributed in the center and south of this continent, including the western Mediterranean arch. They are also present in the British Island, France, Co…
Crayfish in Fish Tanks
- In general, the fish that live in fish tanks are those are sold in shops, which come from breeding centers, which means that they were born in captivity, and not in the river. These have gone through a specialized sanitary supervision, so they are fit to live in a fish tank. It is not recommended to put river fish in a fish tank. The rivers do not always have all the purity that we …
Crayfish´S Reproductive Method
- Crabs have different ways to attract their couples, as it can be by employing pheromones, acoustic or vibratory media, and even visual means, such as the fiddler crab, which is one of the most boastful crabs in terms of courtship. They carry out internal fertilization, and the copulation is performed belly to belly. This mating takes place just after the female has molted its exoskele…
Funny Facts About The Crayfish Reproduction
- According to the most recent studies, prostitution has been shown to exist not only in human beings, as we all know, but also among crabs! The Researcher Patricia Backwell of the Australian National University said in a publication, that fiddler crabs understand sex as an exchangeable value. The fiddler crabs males differ from the females, due to their pincers which are considerab…
Crayfish´S Care
- In general, the best thing is not to have any animal in captivity, because in spite of all the cares we can offer to them, they will never be better in another part, but in their natural environment. Crabs are animals that have a digestive system very different from that of humans, but people insist on feeding them as if they were one of the family. The alimentation is the most important care that …

Fossil record
Fossil records of crayfish older than 30 million years are rare, but fossilised burrows have been found from strata as old as the late Palaeozoic or early Mesozoic. The oldest records of the Parastacidae are in Australia, and are 115 million years old and the crayfish Mongolarachne chaoyangensis and Cricoidoscelosus aethus are at least 129.7 million years old, making them both one of, if not, the oldest known crayfish to date.

Uses
Crayfish are eaten worldwide. Like other edible crustaceans, only a small portion of the body of a crayfish is eaten. In most prepared dishes, such as soups, bisques and étouffées, only the tail portion is served. At crawfish boils or other meals where the entire body of the crayfish is presented, other portions, such as the claw meat, may be eaten.
