The aquarium Oceanarium

A note from Mom and Dad: This post is part of our Kid’s View series, written by Hazel (age 9). It’s her take on the Singapore Oceanarium, formerly S.E.A. Aquarium, with tips for visiting with kids at the bottom.

After we wrapped up at the waterpark, the aquarium was really fun. Here, I’ll tell you why!

Before we could go into the Singapore Oceanarium, we had to scan our tickets, which happened to be on my dad’s phone. We got in pretty quickly after that. The first room that we went into was a jellyfish room that was full of different kinds of jellyfish!!! (my kind of room!) It was a really nice room, there were at least five medium sized fish tanks full of jellyfish and on the far back wall there was one big jellyfish tank that was the size of a big couch.  I counted at least 193 jellyfish then I lost count (my parents took forever to get out of that room).

Next there was a room with a funny looking fish that had his mouth open something like 6 inches and you could see right through him. It cracked my dad and me up (while we were having fun my mom was looking at a different room). After that exhibit there was a room with some prehistoric bones. It was pretty cool! 

The next room happened to not be a room at all. It was one of those round tube things that you walk through and normally they are full of different types of fish but this one was full of SHARKS!!! It was awesome!

That’s why the aquarium Oceanarium is amazing!!!!!!!!!!!!!

Stick with me here and join us in our next adventures in Bali!

Parents’ Notes: Singapore Oceanarium

• What it is: This is the former S.E.A. Aquarium at Resorts World Sentosa, rebuilt and expanded and reopened in July 2025. It has about 22 zones and more than 40,000 animals.
• Hours: Usually 10am–7pm daily. Hours sometimes shorten for private events, so check the official site before you go.
• Tickets:
  • International visitors pay S$50 per adult and S$39 per child on weekdays, or S$55 and S$43 on weekends and holidays.
  • Children under 4 get in free with no booking needed.
  • A cable car + Oceanarium combo gives a 5% discount.
• Getting in: Have your e-ticket ready on your phone. Most delays happen before the scan point.
• Time needed: 3–5 hours. It runs longer if you stop for feeding sessions and the interactive pools.
• Beat the crowds:
  • We arrived in late afternoon on a weekday in September, and the crowds weren’t bad. We hear the first 60–90 minutes after opening are the calmest.
  • Most groups bunch up in the jellyfish galleries at the start (including us), so you could head straight to Shark Seas and Open Ocean first, then circle back.
• Don’t miss:
  • The jellyfish habitats early in the route.
  • The Shark Seas tunnel, with sand tiger, scalloped hammerhead and sandbar sharks overhead.
  • The fossil display, which is Hazel’s “prehistoric bones.”
• Extras: The free Oceanarium app includes an AR feature about how sharks reproduce. Feeding times change, so check the daily schedule when you arrive.
• Food: Outside food and drinks aren’t allowed.
