The St. Petersburg Oceanarium is a unique venue in St. Petersburg, a true "underwater museum" with live exhibits that allows you to peek into the depths of the world's oceans without leaving the city center. As the only facility of its kind in the Northern Capital, it offers visitors a fascinating journey into the world of marine and freshwater fauna. This modern complex is equally engaging for both adults and children.
The oceanarium's collection is impressive in its scale and diversity. Spanning approximately 5,000 square meters, it houses dozens of tanks containing over 4,500 living creatures representing about 150–200 species from across the planet. Here, you can encounter inhabitants of rivers and lakes as well as residents of distant seas and oceans—from vibrant tropical fish, moray eels, and rays to graceful sharks and playful seals.

One of the main highlights of the oceanarium is the 750,000-liter main tank featuring a 35-meter underwater tunnel equipped with a moving walkway. Walking through it creates a complete illusion of being submerged on the seabed. Additionally, visitors can witness exciting shark and seal feeding shows. The Oceanarium is conveniently located within the "Planeta Neptun" shopping and entertainment mall, making your visit even more comfortable.
