If you want to spend quality time with children and learn about marine life in all its details, all you have to do is visit the Avrikarium (aquarium) located in the heart of the zoo in Wroclaw. This aquarium includes more than 5,000 species of fish that live in a transparent tank with a height of 18 meters, which means that you can see sharks, turtles, seals, seaweed, and others.
