Dubai Aquarium and Underwater Zoo is one of the world's largest indoor aquariums, situated within The Dubai Mall in the heart of Dubai, United Arab Emirates. The facility holds 10 million litres of water and is home to over 33,000 aquatic animals representing more than 300 species, including 400 sharks and rays. A dramatic 48-metre, 270-degree glass tunnel allows visitors to walk beneath the main tank and marvel at sharks, rays, and schools of fish at close range. The Underwater Zoo takes guests through three ecological zones — rainforest, rocky shore, and ocean — where they encounter crocodiles, penguins, otters, jellyfish, piranhas, and more. Penguin Cove offers a climate-controlled habitat for Gentoo penguins. The attraction combines awe-inspiring marine spectacle with education about aquatic ecosystems, making it a top family destination in Dubai.
