The Underwater City – Exploring the Coral Reef for Kids
Dive into the most spectacular ecosystem on Earth — the coral reef! Discover amazing ocean animals in this beautifully animated nature story for children aged 2–7.
About This Video
Below the surface of tropical seas, a coral reef is as busy as any city — and every apartment in this underwater city is occupied. This animated nature story dives into the reef to meet clownfish hiding in anemones, sea turtles gliding through the coral, parrotfish crunching coral into sand, spotted moray eels peering from crevices, rainbow-coloured wrasse and clouds of tiny silver fish moving as one. Children discover that coral is not a rock or a plant, but a living animal colony.
Perfect for children aged 2 to 7 who love ocean animals. Brilliant before a snorkelling holiday, an aquarium visit or an ocean topic at nursery. Pairs well with a visit to a coral tank at a local aquarium where children can spot species they have met in the video. Free to watch.

Parents' Questions
Which ocean animals do children meet in The Underwater City reef story?
In this coral reef story, children encounter clownfish (who live inside stinging sea anemones without getting stung), sea turtles (who glide slowly through the coral eating jellyfish), parrotfish (who crunch coral with their beak-like teeth and produce the white sand on tropical beaches), moray eels (who live in reef crevices), brightly coloured wrasse, shoals of silver damselfish, starfish and sea urchins. The reef is treated as a neighbourhood where every creature has a role — making ocean biology feel like meeting a community.
Does this coral reef video explain what coral actually is?
Yes — this is one of the most important revelations in the story. Most children (and many adults) assume coral is a rock or a plant. This video clearly shows that coral is actually a living animal — or rather, millions of tiny soft animals called polyps living in hard calcium shells they build themselves. When you see a coral reef formation, you are looking at the accumulated shells of billions of polyps built up over thousands of years. Children who learn this fact never look at a coral image the same way again.
What age is The Underwater City coral reef video designed for?
Designed for children aged 2 to 7. Young children are captivated by the colours and the diversity of creatures. Children aged 5 to 7 absorb the ecological facts — what each species eats, where it shelters, how the reef community works together. Widely used in school ocean and sea life topic weeks. Absolutely brilliant before an aquarium visit — children arrive armed with specific animals to look for and facts to share with whoever is standing next to them at the tank.
