Prawns and shrimp taste similar, but there are many anatomical differences between these two crustaceans: - __Classification__: While prawns and shrimp belong to the same *Crustacea* subphylum, these crustaceans occupy different suborders. Shrimp belongs to the sub-order *Pleocyemata*, which also includes lobster, crab, and crayfish. Prawns belong to the sub-order *Dendrobranchiata*. - __Gills__: Shrimp and prawns have different gill structures. Shrimp have lamellar gills, also known as plate-like gills, and prawns have branching gills. - __Shape__: Prawns have straight bodies, while shrimp bodies bend and curl. On a prawn, the exoskeleton segments overlap from front to back. On a shrimp, the second segment of the exoskeleton overlaps the first and third segments, which makes their bodies curl. - __Legs__: Shrimp have two front pincers and two pairs of claw-like legs. Prawns have pincers on their first pair of legs and larger second pincers, and claws on three pairs of their legs. Prawns have longer legs than shrimp. - __Eggs__: Shrimp carry their fertilized eggs on the underside of their bodies, while prawns release their eggs into the water. You can use prawns and shrimp interchangeably in cooking, but the flavors may differ depending on breed and if freshly caught, farmed, or previously frozen.
