Shrimp and Prawn: Exploring the Differences and Similarities

If you're a seafood lover, you've probably heard the terms shrimp and prawn used interchangeably. While they may look similar and belong to the same family, there are some key differences between the two.

In this article, we'll explore the biology and classification of shrimp and prawn, as well as their culinary insights.

Shrimp and prawn are both decapod crustaceans, meaning they have ten legs and a hard exoskeleton. However, they belong to different suborders and have distinct anatomies.

Shrimp have claws only on two of their five pairs of legs, while prawns have claws on three of their five pairs. Prawns also tend to have longer legs and a second pair of claws on their third abdominal segment.

When it comes to cooking, shrimp and prawns can be used interchangeably in many recipes. However, prawns tend to have a sweeter and more delicate flavour than shrimp.

Both are healthy sources of protein, omega-3 fatty acids, selenium, and vitamin B12.

Species and Suborders

Shrimp and prawns are both decapod crustaceans, which means they have 10 legs and a hard exoskeleton. They belong to the same order, Decapoda, but are classified into different suborders.

Prawns are classified as Dendrobranchiata, while shrimp are classified as Pleocyemata.

Physical Characteristics

One of the main anatomical differences between prawns and shrimp is their gills. Prawns have branching gills, while shrimp have lamellar gills.

Prawns also have longer claws on their first three pairs of legs, while shrimp have shorter claws.

In terms of body segmentation, both shrimp and prawns have a head, thorax, and abdomen. The head has two pairs of antennae and compound eyes, while the thorax has five pairs of legs. The abdomen has six segments, with the first segment being fused with the thorax.

Shrimp and prawns also have a flexible exoskeleton that they must shed periodically in order to grow. This process is known as moulting.

During moulting, the old exoskeleton splits and the shrimp or prawn wriggles out of it. The new exoskeleton is soft and takes a few days to harden.
