The aquarium space is divided into 16 thematic zones, each dedicated to a specific ecosystem — from rivers and swamps to the endless expanses of the ocean. Visitors can explore the "Amazon Forest," look into the "Deep Sea," and even walk through a thrilling underwater tunnel, watching sharks and rays swim overhead. The exhibition is designed as a "fantastic underwater journey" that introduces the diversity of underwater life from around the world.
In addition to its entertainment function, the COEX Aquarium plays an important educational and scientific role. It is not just an exhibition, but a real research center where scientists study marine biology. The aquarium's main mission is to educate visitors, popularize knowledge about the aquatic world, and draw attention to environmental conservation issues.
