How Many Types of Prawn Are There?

There are approximately 2,000 species of prawn, which are mostly known as shrimp. They are found in all types of waters, including freshwater lakes and streams as well as shallow and deep water.

Prawn is a common name used to refer to shrimp. The term "prawn" is used more often in the United Kingdom, Commonwealth nations and Ireland. Shrimp is often used to describe the smaller species of the crustacean that are wider and possess a shorter dorsum. Smaller species are never described as prawn. In the Commonwealth regions, shrimp are used to describe crustaceans 3 inches or smaller, while prawn is used to describe those up to 12 inches in length. In the United States, the word "shrimp" is used more often than "prawn."
