The Oceanarium is home to 14,000 marine creatures from around 277 species, all indigenous to the Philippines and Southeast Asia. Its sheer size and diversity make it one of the world's best public aquariums. The Oceanarium is a stunning walkthrough of the watery depths featuring seven sections and containing 3,000 cubic meters of seawater. At the heart of a 55-meter journey inside the Oceanarium is the main attraction - a 220° curved walkway tunnel with a spectacular underwater view of amazing sea creatures swimming overhead.
The water source for the Oceanarium is filtered water from Manila Bay. A special process is done to ensure that the seawater is suitable for marine life. It has an educational activity area, unique function rooms for special events and bi-level shark and stingray viewing facilities.
