Amid the scandals over menu misrepresentations in the food service industry, the Susami Crustacean Aquarium in Wakayama Prefecture is stirring the pot with an exhibition to help consumers recognize fraudulent practices of this kind.

The aquarium, located in the town of Susami, has been holding the exhibition since mid-November to teach visitors how to distinguish between different types of prawns.

A tank with two different kinds of prawns has a notice that reads: "Can you see the difference? The fraud on prawns."
