Marine and freshwater species release special chemicals, or pheromones (FEH-re-moans), into the water along with their waste through special glands on the antennae. What is the difference between a crab and a shrimp? Shrimp belong to the suborder Pleocyemata, while prawns are part of suborder Dendrobranchiata. Part of the confusion originates with the association of smallness. Scientific classifications aside, the lines still get blurred when purchasing them in your local grocery store or seafood purveyor. Plankton is made up of plants and animals that live in open water and are at the mercy of ocean currents. Prawns have longer legs, as well. They are used mostly to detect odors.

That creates problems with shrimp-like species that are not small. In the use of common names for species, shrimp is applied to smaller species, particularly species that are dorsoventrally depressed (wider than deep) with a shorter rostrum. This behavior is believed to prevent them from being eaten by predators. Just check the shell if you want to know what crustacean you purchased without making a trek out on a shrimp boat. On this Wikipedia the language links are at the top of the page across from the article title. Because there are many exceptions to the basic features, however, a satisfactory inclusive definition of all the Crustacea is extraordinarily hard to frame. Shrimp sizesare represented by numbers, such as 12/15, which stand for the total number of shrimp in a pound (in the case of our example, 12/15 stands for 12 to 15 shrimp/pound). This gives the two crustaceans different habitats, and thus, different flavor profiles: shrimp will be naturally saltier in flavor than prawns.
