The word used in America is Shrimp. Though people that know what they are talking about may call the larger prawn, the restaurants and people eating them will just call them giant shrimp.

I didn't know this, so I looked it up for us. 1, They are both very common in restaurants, yes (and very nice too, especially in Spanish Paella or spicy tomato and prawn soup). 2. http://www.wisegeek.com/what-is-the-difference-between-shrimp-and-prawns.htm They look similar, taste similar but are actually 2 different creatures. So thank you for educating me tonight :)

They are the same by their "zoological view". But in Culinary they are not the same. Shrimp and prawns have a difference on the basis of their size. “Prawns” are considered to be larger, while shrimp are smaller.

Good Question=)
