Japan’s Kori no Suizokukan, located in Kesennuma, Miyagi Prefecture houses a collection of 450 specimens of 80 or so different species of marine wildlife captured at a nearby port. But there’s one major difference that separates this aquarium from any other — all of the wildlife is frozen in massive blocks of ice.
A flash freezing technique is used to keep the specimens in optimal conditions at all times. Spectators are limited to only a few minutes of viewing because of the -20 Celsius temperatures inside of the aquarium’s depths. All attendees must wear a special suit made for preventing exposure. Without the suits, most visitors would experience severe pain within minutes.
