The Sea World ZOO at Prague’s Výstaviště is a permanent exhibition of marine as well as freshwater fish and other animals with a total number of 360 species. It is located in the upper part of the complex, a short walk from the tram stop and is accessible throughout the year.

Inside you will find a total of 60 aquariums, the largest of which has a volume of 100,000 litres and is home to sharks. Overall, there are 260,000 litres of water here. Here you can see stingrays, morays, lionfish and, for example, horseshoe crabs. Another attraction is the 25-meter-long coral cave with aquariums in the rock, mainly featuring animals from South America, a unique transparent tank with 27,000 litres of fresh water, where cichlids, piranhas, water turtles and many other species live. The ZOO also has a floor projection that reacts to movement and offers effects that will especially interest the smallest visitors.

The exhibition has had the status of a zoological garden since 2006.
