• The Great Barrier Reef is near 18 mln years old. The area of the reef is more than 230 thousand sq km.

• Coral reefs are usually called the “live rocks”.
• They are built of thousands of polyps, which are closely set to each other. They make up a lime base and can get off easily.

• Among the corals swims a unique animal – a horse-fish. It looks like a chess figure and has a wonderful tail, that helps it swim very fast. The tail can also help the horse-fish to hold to some plant or a coral polyp. Males, not females, usually bring up babies.
