Singapore Oceanarium

Formerly S.E.A. Aquarium, Singapore Oceanarium is Resorts World Sentosa's marine institute — an immersive walk-through experience across zones including In the Beginning, At the Surface, Sunlight, Into the Deep, and A New Horizon, blending large habitat tanks with digital storytelling and touch-table interactives that keep younger kids engaged.

General admission runs from roughly $35–55 depending on residency status and peak/off-peak timing (children under 4 enter free). Open daily, 10am to 7pm. Combine with Universal Studios Singapore or Adventure Cove Waterpark for a longer Resorts World Sentosa day.
