On 6 September, opening day of the Primorye Oceanarium, visitors got a glimpse of inhabitants of Russian rivers and lakes, tropical and Arctic seas and oceans. The administration invited visitors to the dolphinarium to watch the training of sea mammals - white-sided dolphins, a walrus, and white whales.

Director of the Primorye Oceanarium of the Far Eastern Department of the Academy of Sciences, Vadim Serkov, directed the visitors’ attention to one white whale’s grey head, noting that the species is born completely blue and then gradually grows paler and paler. He added that a white whale eats 20 kilos of fish a day.

The Primorye Oceanarium features wildlife of all the planet’s oceans. It has on display over 500 species of sea and freshwater animals, including invertebrates, fish, birds and sea mammals.
