Aquarium Near Me on Sentosa: Singapore Oceanarium's Jellies, Sharks and Manta Rays

Singapore Oceanarium, at 24 Sentosa Gateway inside Resorts World Sentosa, opened on 24 July 2025 in the space that S.E.A. Aquarium had filled since 2012, and adult tickets start from S$55. For anyone on Sentosa searching aquarium near me, this is the one: triple the old footprint, 22 themed zones and more than 100,000 animals in 49 habitats, with no time limit once inside.

S.E.A. Aquarium opened on 22 November 2012 and closed on 30 April 2025 for the rebuild. Less than three months later it reopened as an ocean institute. Next door, the Research and Learning Centre, certified Green Mark Platinum Zero Energy, hosts marine science work that includes a five-year collaboration with the National University of Singapore and a project with NTU's Earth Observatory of Singapore.

The route is arranged as a journey through time and depth. You start In the Beginning, under the Drop of Water dome, where projected plankton swirl overhead at a scale no microscope gives you. The path then climbs to the coast, drops through the sunlit shallows, passes into the deep and ends in the Abyss before a final zone called A New Horizon. Budget about 3.5 hours.

In Ocean Wonders, one of the world's largest Kreisel habitats holds thousands of Moon Jellies, and cylindrical tanks around it show Atlantic Sea Nettles and Fried Egg Sea Jellies, many bred in-house by the aquarists. Next, Ancient Waters puts life-sized animatronics of the armoured Dunkleosteus and the predatory Xiphactinus beside living holdovers such as the Australian Lungfish, Arapaima, Horseshoe Crab and Epaulette Shark.

Spirit of Exploration is built around the Jewel of Muscat, a reconstruction of a ninth-century Omani dhow, with the Pier Adventure suspended web above it and Explorer's Nook café alongside. Singapore's Coast follows, with Archerfish and Barred Mudskippers in mangrove habitats. Pelago's March 2026 review singled out the Rock Pool, where cleaner shrimps nibble a dipped hand, and the Art-quarium touch table, where children draw a digital fish and give it a name.

In Shark Seas, the Shark Tunnel puts Sand Tiger Sharks, Scalloped Hammerheads and Sandbar Sharks overhead and to each side. Coral Gardens has a crawl tunnel through the Moray Eel rockwork, and Reef Animals shows Weedy Seadragons beside a Kelp Forest, with a window into the Aquarist Lab where hatchlings and plankton cultures are raised.

Further on, the Migrators zone holds Indo-Pacific Bottlenose Dolphins and Japanese Pineapplefish, whose glow likely helps them communicate. The Abyss ends the walk with a life-sized replica of a Triton deep-sea submersible, a whale fall skeleton under projection mapping, and live tanks of Japanese Isopods, Deepsea Akaza Prawns and Australian Ghostsharks. The marine mammal viewing panel closes at 3pm on Mondays and all day on Tuesdays for maintenance, so dolphin fans should pick another weekday.

The Resorts World Sentosa booking page lists admission from S$55 for adults aged 13 to 59 and from S$43 for children aged 4 to 12 and seniors 60 and over; under-fours enter free. Peak dates cost more, and since 1 January 2026 one rate applies to residents and tourists alike. This October, a same-day bundle with Universal Studios Singapore's Halloween Horror Nights 14 starts from S$109.

During peak periods you book a time slot and get a 15-minute grace period; slots cannot be changed after booking, and a group enters together only if everyone holds the same slot. Strollers and wagons are allowed, flash photography is not permitted and professional production cameras stay outside. Need to leave? Get your hand stamped at the exit and come back the same day with your ticket.

There are no lockers inside; the nearest are outside Universal Studios Singapore and at Coach Bay, so pack light. Outside food and drinks are not allowed apart from baby food, formula and special-diet meals. On site, Explorer's Nook, Ocean Bites and Tide Deli cover snacks, while Ocean Restaurant serves a sit-down meal facing the Open Ocean habitat. Every outlet has vegetarian choices, but none is Halal-certified.

Pelago's 2026 review recommends going early in the morning or around 4pm on a weekday, and warns that midday turns the narrow early galleries into a sardine tin. Opening is 10am on weekdays and 9am on weekends and public holidays, and a weekday 4pm arrival still catches the Open Ocean dive feed and finish before the 7pm weekday close.

Skip the Pier Adventure web unless your children are set on it. It costs an additional ticket on top of admission, and the Jewel of Muscat looks just as good from the floor of Spirit of Exploration. Plan B if your slot is sold out: the Singapore Oceanarium Store near the exit needs no ticket, and Adventure Cove Waterpark is also inside Resorts World Sentosa.

On weekdays the corridors fill with school groups on educator-led programmes, which run from 45-minute sessions to the 3.5-hour Insider Experience, some in Mandarin. Families with young children make for the Rock Pool and Art-quarium. Adults get their own nights too: on 19 September 2026 the oceanarium held its first Silent Disco, S$55 with a drink, with DJs set up among the sea jellies and the Ancient Waters predators.

Take the North East Line or Circle Line to HarbourFront, follow Exit E into VivoCity and ride the Sentosa Express from Level 3 one stop to Resorts World Station. Follow the signs to the end of the row of shops, turn right, pass the Universal Studios Globe, and the ticket counter sits left of the oceanarium entrance. Bus RWS8 from VivoCity bus stop 14141 drops you at the resort too.

For the return, walk instead of riding. From the oceanarium entrance, cross the small bridge, head down to the waterfront viewing platform and follow the water to the Sentosa Boardwalk, which carries you over the channel to Level 1 of VivoCity. It is the same route the oceanarium gives walkers coming in, run backwards, and it needs no ticket.
