Overview and Location: Southeast Asia’s Largest Oceanarium
The Singapore Oceanarium sits right on Sentosa Island, inside Resorts World Sentosa. It’s the biggest aquarium in Southeast Asia now, with 22 immersive zones and an 18-million-litre tank that holds over 40,000 marine creatures from 120 species. That’s a lot of fish, right?
The transformation from S.E.A. Aquarium to Singapore Oceanarium happened in July 2025, according to Marketing Interactive. It’s not just a name change; the space tripled, and the focus shifted to conservation and education. They even partnered with the National University of Singapore for research. So you’re not just looking at pretty fish; you’re supporting real science.
Getting there is easy. Take the MRT to HarbourFront station, then hop on the RWS8 shuttle bus for just S$1. Or take a cable car from Mount Faber for stunning views. If you’re driving, use the Sentosa Gateway and park at Resorts World. We recommend taking the shuttle; it’s cheap and drops you right at the entrance.
Once you arrive, you’ll see a map near the entrance. The aquarium is laid out in one continuous path, so you can’t get lost. Just follow the flow and enjoy the ride.
Key Takeaway: The Singapore Oceanarium is the largest in Southeast Asia, located on Sentosa Island, and easy to reach by MRT, shuttle, or cable car.
Bottom line: The Oceanarium’s massive size and convenient location make it a must-visit for anyone in Singapore.
Top Attractions: Must-See Zones and Exhibits
With 22 zones, you can’t see everything in one go. But we’ve picked the ones you absolutely cannot miss.
Open Ocean Habitat
This is the heart of the aquarium. A window that’s 8.3 meters tall and weighs 250,000 kg gives you a front-row seat to manta rays, hammerhead sharks, and thousands of schooling fish. It’s like watching IMAX but real. The tank holds 18 million litres of water, that’s about 7 Olympic swimming pools.
Ocean Wonders (Sea Jelly Heaven)
You’ll walk into a room filled with glowing jellyfish. There are moon jellies, sea nettles, and even fried egg jellies. One tank holds 5,000 moon jellies floating like aliens. It’s mesmerising. This zone is often under-hyped, but it’s a total highlight.
Ancient Wonders
Step back in time. This zone features prehistoric fossils like the Dunkleosteus and living fossils like paddlefish and horseshoe crabs. There’s even a walking shark, the epaulette shark, that uses its fins to crawl along the bottom.
Whalefall and Seamounts
A life-sized whale skeleton shows what happens when a whale dies and sinks to the deep-sea floor. It becomes an oasis of life. This exhibit is dark and moody, exactly like the deep ocean.
Interactive Zones
At Singapore’s Coast, you can put your hands in a touch pool with starfish and cleaner shrimp. The shrimp give you a free manicure by nibbling dead skin. It’s weird but fun. There’s also a digital screen where you can learn about tripod fish and the Dumbo octopus.
Regenerate
Pro Tip: Visit the sea jelly zone early in the day when it’s less crowded. The low lighting makes the colors pop even more.
Bottom line: The Open Ocean, sea jelly zone, and interactive coast are the must-see exhibits that make the aquarium unforgettable.

Visitor Experience: Shows, Programmes, and Behind-the-Scenes
Beyond the tanks, the aquarium offers experiences that make your visit even cooler.
Animal Spotlights and Feeding Sessions
Throughout the day, aquarists do feeding presentations at the Open Ocean, Shark Seas, and Coral Garden. Check the schedule at the entrance. You’ll see stingrays gliding up to eat, and sharks going into a feeding frenzy (don’t worry, it’s safe).
Behind-the-Scenes: Aquarist Lab
For an extra fee, you can take a 30-minute tour of the Aquarist Lab. This is where they breed sea jellies, seahorses, and raise baby fish. You’ll also visit the quarantine room. As described in Little Day Out’s coverage, tours run at 11 am, 1 pm, 2 pm, and 3 pm. Book online.
Our tip: sign up for the 11 am tour. The lab is quieter then, and you’ll see more active feeding.
Interactive Play Areas
Kids love the Pier Adventure, a suspended net above the Jewel of Muscat ship replica. It costs a few extra dollars but burns off energy. There’s also a themed cafe, Explorer’s Nook, with cute sea-creature pastries.
Pro Tip: The behind-the-scenes tour is worth the extra S$30. You’ll never look at jellyfish the same way again.
Bottom line: The aquarium offers feeding shows, a behind-the-scenes lab tour, and interactive play areas to deepen your experience.
Conservation and Education at the Aquarium
The Singapore Oceanarium isn’t just a tourist attraction; it’s an ocean institute. They have a Research & Learning Centre right next door with labs, seminar rooms, and immersive learning labs. Their partnership with NUS (National University of Singapore) focuses on marine biology and conservation.
Breeding Programmes
They have successful breeding programmes for sea jellies, seahorses, and even some shark species. You can see the nursery tanks through the windows in the lab. They also rescue and rehabilitate injured turtles and release them back into the wild.
What You Can Do
At the end of the aquarium, there’s a zone called “Ocean’s Future” that shows what happens if we don’t protect the ocean. Then they give simple actions you can take: use less plastic, choose sustainable seafood, and support marine reserves.
While you’re travelling, consider how you can offset your carbon footprint. For example, if you’re planning long flights, you might want to read about blue light blocking glasses to reduce eye strain during the journey. And for health-conscious travellers, vegan supplements can help maintain energy levels during a busy itinerary.
Regenerate
Key Takeaway: The aquarium’s research partnerships and breeding programmes make it a leader in marine conservation, not just a fun day out.
Bottom line: Your visit directly supports conservation research and education efforts that protect ocean life.
