In the mysterious and deep 180 Shark Bay Submarine Tunnel, there are three or five groups of sea fish, which are colorful. They shuttle back and forth in the marine life exhibition area constructed by acrylic glass. The blue and bright artificial sea water is swaying and colorful, which makes people feel like they are in the "underwater world".
"Compared with the previous generation of marine parks, the third generation of marine parks introduced acrylic glass technology, which made the construction of large-capacity biological exhibition areas possible." Zhang Zheng, Assistant Chairman of Wuyishan Polar Ocean Park, introduced. Acrylic glass is a kind of molecular material with high plasticity. Compared with ordinary glass, acrylic glass has better transparency, stability, weatherability and compression resistance. It is used to construct marine life exhibition area. On the basis of increasing exhibition area, acrylic glass can withstand stronger pressure, so it can accommodate larger water body and exhibit more abundant marine life.
"This cylindrical tank has the largest volume in China. It has a diameter of 5 meters and a height of 9 meters. It can accommodate nearly 200 cubic meters of artificial sea water. We will show the marine fish of different depths of life here." Before the giant cylindrical ocean tank named "Dinghai Needle", Zhang Zheng introduced the differences between Wuyishan Polar Ocean Park and other Ocean Parks in our province: the construction of large capacity water containers changed the window display form of traditional ocean parks, and introduced the concept of "polar region", which added polar bears, polar wolves, and marine mammals on the basis of displaying a variety of fish and marine mammals. Arctic foxes, penguins and other animals from the polar region.
