Differences Between Prawns and Crawfish

Prawns and crawfish are two different types of freshwater crustaceans, but there are some notable differences between them.

Here, we will discuss the various physical and behavioral characteristics that distinguish these creatures from one another.

Prawns mainly live in saltwater habitats such as oceans or seas, while crawfish are predominantly freshwater creatures found in rivers or swamps.

The body shape of prawns is linear, sleek and slender, whereas crawfish have a curved shape with a noticeable hump on their back.

Conversely, crawfish have larger pinchers that they employ for similar purposes.

Prawns also tend to have shorter legs than crawfish; however, their legs are usually thicker in proportion to their body size.

In contrast, crawfish possess longer legs that can be thin in comparison.

Finally, there is a distinction between the antennae of prawns and those of crawfish.

Prawns have straight antennae with little curvature or bend, while the antennae of a crawfish curve sensuously over its head region.

In summary, these subtle yet distinct differences help us differentiate between prawns and crawfish.

Also, prawns have ten slender legs that extend from their body while crawfish has eight walking legs plus two large claws.

Although both crustaceans have antennae on their heads used for sensing their environment, prawns’ antennules and antennae are longer, thicker and more whip-like compared to those of the crawfish.

When it comes to size, prawns are generally larger than crawfish in length measuring between six to sixteen inches while crawfish tends to be smaller about three-eight inches.

In terms of coloration, both creatures come in various shades like brownish-green or grey-brown for freshwater species giving them camouflage capabilities.
