Contrary to popular opinion, 'prawns' or 'shrimp' is not merely a dialect differentiation Yes, in general, the Americas prefer 'shrimp' whereas Australia prefers 'prawns'. The UK uses both, differentiating by size, the smaller ones being 'shrimp' and the larger 'prawns'. However, while it is generally true that shrimp are smaller, it isn't necessarily a size issue either.
There are taxonomic differences between the two. This Spruce Eats article explains. As does this from USA Today.

An example of the confusion is that the famous Santa Barbara spot prawn is actually a shrimp!
Thanks! The business I’ve mentioned grows Litopenaeus vannamei in suborder Dendrobranchiata aka Pacific white-leg shrimp, "White Shrimp" or "King Prawns" on the prawn side of the illustration you shared.
