The first things to see in the main building of the Museum of the World Ocean are the aquaria. There are 14 of them, both sea and fresh water, about 16,000 litres in total volume, containing over 300 creatures and 133 species from different parts of the world's oceans, including rays, sharks and piranhas. Then there is Russia's biggest sperm-whale skeleton, found on the Vistula Spit in 2004. There is an interactive display for children, Water Lab, where they show various tests and experiments.
