Know the sizes of Prawns

Hi,<br> I am really sick and tired of Ocean Basket and other seafood outlets that ******** the public about the various sizes of prawns. Please stop serving normal 100-150 mm in size prawns as KING prawns. There is a recognized standard for the size of prawns. A King prawn is approx. 350 mm. It would appear that Queen prawns are also 100 - 150 mm in size, really!!
