Attraction

Singapore Oceanarium.

Last reviewed · 1 October 2026 · Formerly S.E.A. Aquarium

The Singapore Oceanarium is the 2026 rebrand of S.E.A. Aquarium at Resorts World Sentosa — the same site reworked with new deep-sea halls, updated exhibits and a broader marine-conservation storyline. Over 100,000 marine animals from around a thousand species in forty-nine habitats; the Open Ocean viewing panel remains the signature stop.

The circuit

The route begins at the Karimata Strait zone (freshwater and estuarine species of southeast Asia), moves through the Straits of Malacca into the Bay of Bengal, then onwards through the Arabian Gulf and the Red Sea into the Open Ocean habitat. The Shark Seas acrylic tunnel comes near the end. Expect ninety minutes at a comfortable pace; families with children often take two hours or more.

What to see first

1. Open Ocean. A 36-metre viewing panel into an 18-million-litre tank. Manta rays, scalloped hammerheads and schools of trevally make slow passes.
2. Shark Seas. Acrylic walk-through with sand tigers and silvertip reef sharks overhead.
3. Reef Discovery. Hands-off tactile pools where staff talk through starfish, sea cucumbers and small reef fish.
4. Live dive feeds. Scheduled daily — the board at the entrance has times.

When to go

Peak hours are 11:00 to 15:00. First-hour openings and the hour before closing are the quietest; the Open Ocean panel is often empty enough for extended viewing in those windows. On rainy Singapore afternoons the oceanarium fills quickly as outdoor attractions thin out — plan accordingly.

Accessibility

Step-free throughout. Wheelchairs available on request at the entrance. Hearing-induction loops at the live-feed theatres. Service animals welcome in most areas with advance notice.
