some of my favorite food is seafood, specifically shrimp.  Shrimp and prawn are important types of seafood that are consumed worldwide!
Shrimp is one of my favorite seafood items, I like it with pasta a lot.
Yeah and some shrimp and prawns belong to different suborders of Decapoda, they are very similar in appearance and the terms are often used.
I never knew that. I wonder if I've eaten prawn and thought I was eating shrimp?
well recently there is a distinction drawn in aquaculture literature, which increasingly uses the term "prawn" only for the freshwater forms of palaemonids and "shrimp" for the marine penaeids.
