With a floor space of 47,000 square meters, the Tianjin Polar Marine Museum has more than 2,000 polar marine species from Russia, Canada, Australia and other countries on display.

The museum includes a 30-meter long "touch pond," which gives visitors the chance to "touch and feel" a variety of fish, shrimps, crabs, shellfishes, marine algae and coral. Also, the museum has a performance venue capable of accommodating an audience of 2,000.

The polar marine museum is part of a "polar marine world" project of Haichang (Group) Co., Ltd., which is still under construction. The investment for the whole project is 3.6 billion yuan (about 538 million US dollars).
