here, for instance - study the prawn at 3 o'clock on the left-hand picture (hairy bikers paella) - it's patently the same as the lowest one beneath the lemon in the pic on the right (jamie oliver)

here's nigella's. notice anything familiar about the prawn at the top (tail protruding slightly over dish)?? that's right, it's our old friend the lowest prawn from the hairy bikers photo

claudia roden. working clockwise from top centre: the 1st prawn is jamie oliver's 3rd, the 2nd prawn is JO's 1st, the 3rd prawn is JO's 5th, the 4th prawn is under calamari so hard to make out but prob JO's 2nd. etc

rukmini iyer's paella photo shows the hazards of not using stunt prawns. due to bioluminescence interfacing with the camera flash, all the prawns have become so transparent they are completely invisible
