  • Wow, that's is so beautiful, isn't it, Squeaks?

  • We're looking at pictures of a coral reef

  • a rocky piece of ground in the ocean that's made of, and home to, animals called coral.

  • I wonder if this is the Great Barrier Reef.

  • That's the biggest coral reef in the entire world!

  • It's in the ocean near the country of Australia.

  • See these parts of the picture?

  • Those are the coral!

  • [Squeaks squeaks]

  • You're right, Squeaks, coral look a lot like plants.

  • But they're not!

  • Coral are small animals that make, and live in, a hard, rocky material.

  • Instead of moving around like most animals, they attach to the rocks and stay there for the rest of their lives.

  • That's why they might seem like plants at firstbecause plants don't move around either.

  • One small part of a coral reef can have thousands of coral all living together!

  • Millions of coral over thousands of years have made the Great Barrier Reef.

  • This huge reef is about 2300 kilometers long!

  • That's so long that if you could drive along it in a car, it would take you almost an entire day and night!

  • Like all coral reefs, the Great Barrier Reef is home to lots of different kinds of animals besides for the coralbig and small!

  • Take, for example, the dugong.

  • These big animals eat plantslots of plants!

  • Dugongs spend their whole day looking for and grazing on the seagrasses that grow on coral reefs like the Great Barrier Reef.

  • If the reef didn't exist, these gentle giants wouldn't have enough to eat.

  • Other animals need the rocky coral reef so that they have a safe place to livelike moray eels.

  • They might look fierce and dangerous, but they're really very shy!

  • So they spend most of their time hiding in caves and spaces in the reef.

  • [Squeaks squeaks]

  • Yes, Squeaks, just like how you're hiding behind this desk!

  • Still other animals use the coral reef to hide in a different way, like the cuttlefish.

  • Cuttlefish can change the color of their skin so they look a lot like the coral reef.

  • That helps the cuttlefish hide from other animals that want to eat them!

  • The Great Barrier Reef is an important place for all of these animals, and it's important for people, too.

  • The reef helps protect Australia from the strong waves that storms churn up from the water.

  • We can also make some types of medicine using the plants and animals that live there.

  • But the ocean is changingand that means changes for the Great Barrier Reef, too.

  • Some things people do, like use too much electricity, make the world get a little warmer, including the oceans.

  • As the ocean gets warmer, coral can have a hard time getting enough food,

  • and with fewer coral, the animals that live around them have a harder time finding enough food, too.

  • Another problem is pollution in the oceanchemicals, litter, and other kinds of waste that can eventually make their way into the water and hurt the animals that live there.

  • But people are working on ways to help the animals that live on and around the reef to stay healthy,

  • like learning how to keep pollution from getting into the ocean.

  • And there are things that we can do to help, toono matter where we live!

  • For example, things that go down drains in our sinks or bathtubs can sometimes end up in the ocean.

  • We can help keep the ocean clean by only putting things we're supposed to down the drain.

  • We can also make sure trash ends up in the garbage can or recycling bin where it belongs,

  • which helps keep it from getting into rivers or the ocean.

  • There are lots of awesome living things in the ocean, and if everyone works together, we can help keep them healthy.

  • Thanks for joining us!

  • and we'll see you next time, here at the Fort!
