The terms "shrimp" and "prawns" can be confusing. Even scientists often
use these words inconsistently. Larger shrimp often come from freshwater, are referred
to as "prawns," while smaller shrimp often come from saltwater habitats, are
called "shrimp." The size, "large" typically means that you get
about 40 or less per cooked pound, in comparison to about 50 for
"medium" and 60 for "small". But from a science perspective, both
shrimp and prawns can come from saltwater or freshwater, and there is no
absolute standard for measuring small, medium, or large.
