Both shrimp and prawns are decapod crustaceans. While the shrimp on our dinner plates rarely exceed 3 inches, some can grow large enough to rival their larger cousins. In this list, we will look at the largest shrimp and prawns in the world. Note that the mantis shrimp is not included, even though many believe it to be the largest shrimp. However, mantis shrimp are not true shrimp; they are shrimp-like crustaceans. Keep reading to discover 10 of the largest shrimp and prawns you can find in either freshwater or ocean habitats.
The Difference Between Shrimp and Prawns
In some countries, like the U.K., the name “prawn” is used for both types of crustaceans. However, prawns and shrimp are anatomically distinct groups of crustaceans, with prawns often found in both freshwater and marine environments, depending on the species. Prawns generally have longer thoraxes and shorter abdomens compared to shrimp. They also typically have claws on three pairs of their five pairs of legs.
In contrast, shrimp are generally smaller and have curvier bodies. They have shorter thoraxes and longer abdomens than prawns. Shrimp typically have claws on only two of their five pairs of legs. They are found in both marine and freshwater environments. There are also differences in their gill structure, the way their body segments overlap, and their reproductive behaviors.
