A 83-meter travelator (train-like transportation carriage) moves visitors along the entire oceanarium, via a submerged 6.0mm thick acrylic-window, forming a tunnel. From this tunnel, visitors can see a variety of marine animals, including stingrays, turtles, moray eels, sharks, coral reefs and much more.

The Underwater World provides an array of educational, environmental and edutainment-based programs and projects, such as the Ocean Ambassador, Living in the Ocean and Coral Club. The popular oceanarium also offers several exclusive marine-themed venues for functions.

The Dolphin Lagoon is part of the Underwater World attractions, and is home to several Indo-Pacific Humpback Dolphins, commonly known as the pink dolphins. A variety of performances are scheduled at the Dolphin Lagoon, mostly held during weekends, and some visitors are allowed to interact with the dolphins under the trainer's supervision. The ticket for Underwater World does not include the interaction experience at Dolphin Lagoon, and interested parties must purchase a token for the activity.
