S.E.A. Aquarium is by far, my most favorite attraction in Resorts World Sentosa. It was once the world's largest aquarium. Although it lost that title, it still has the world's largest collection of manta rays.
It is definitely fascinating - strolling along the underwater realm and seeing sharks above you. The glass panels at the Open Ocean wing is also great! There are numerous manta rays swimming, flying around. And sometimes, it feels like they're the ones watching you instead of the other way around. They have bigger space anyway inside the aquarium as compared to the walking grounds for the people.
There are numerous habitats you can venture to. But the most interesting one for me is the Ocean Journey part where you'll see the giant spider alien crab and the jellyfish. I want to be a jellyfish because they're just so chill. Haha!
I'm honestly afraid of the ocean and everything dark below it. But this experience is too mesmerizing to pass up. It's definitely a place to visit when you're in Singapore.
