A maritime museum in Pakistan's most populous city, Karachi, is housing an unlikely trio for a whale and sea lion show that begins this week and owes its existence to the growing role of Russia in the international marine-mammal trade.

A trained beluga whale, dolphin, and sea lion will perform for the public three times a day in "a water show that will be the first of its kind to take place in Pakistan," according to "The Express Tribune."

A "large pool...built expecially for the purpose" sits in a stadium that holds around 2,000 people at the Maritime Museum, near a Pakistani Navy training and educational facility, PNS Karsaz.

The animals will jump, sing, and "give a stellar performance" once the public show begins next week, the report adds.
