The acid in the citrus forms an extremely low pH condition to denature the fish protein networks, much the same as heating would. This results in the seafood becoming opaque and more firm in texture.
As the pieces of fish sit in the marinade, the citric acid from the juice slowly causes the flesh's proteins to denature, in very much the same way that heating will. The result is raw fish with the opaque appearance and firmed texture of cooked fish.
