A coral reef is a giant city under the sea! Coral reefs are home to almost a quarter of all plants and animal species in the entire ocean! They can expand up to almost 100 miles from the sea shore. The reefs can cover less than one percent of the ocean floor. Also, reefs can be found in the coastal waters of almost 100 countries! Coral reefs are found in the Pacific, Atlantic, and Indian Oceans. Corals also live in warm waters all around the world. More than 4,000 different kinds of fish, including exotic fish live in and around coral reefs. There are more than 750 different types of reef-building corals in the ocean! Also, when coral colonies grow, they take the shape as many different looking things. Some can even look like antlers! They are islands made from tiny sea creatures. Coral reefs are found in the Pacific, Atlantic, and Indian oceans. Some times they look like very large rocks from far away. They are very big places!

Coral reefs are built by small animals called coral polyps and these are very important animals. Coral polyps are related to jellyfish and sea anemones. Here are some facts you need to know about coral polyps. Most of them are .25 to 1 inch in size (.63 to 2.5 cm) wide. Some can grow as wide as 12 inches (30.5 cm). Polyps can usually grow about 0.2 to 8 inches (0.5 to 20.3 cm) per year. They can be red, pink, yellow, brown, blue, orange, purple, or green! They like to eat plankton and sugar made by aglae. They have four predators such as the parrotfish, crown-of-thorns starfish, worms, and even snails. Coral polyps live in warm, shallow, clean ocean waters along the coasts of Australia, southern North America, South America, Africa, Southeast Asia, and tropical islands. The polyps usually live about 2 to 3 years, though some species can live much longer. Coral polyps are very important to the reefs.

There a lot of reasons why coral is so fragile. When swimmers and divers step on coral it can damage the corals and hurt animals in them. When people create water pollution and oil spills that can cause harm to corals. Also when people throw explosives into the ocean everything in the ocean is all gone. When people look at the reefs after they have been blown up everything is all brown and there is some broken coral. Some scientists are trying to convince people not to use explosives to catch fish at the coral reefs because one reef in Indonesia was destroyed by people trying to catch fish with explosives. The reason why people do this is because when you throw bombs into the water it stuns fish that are nearby and this makes it easier for people to catch. Also, if trash is not thrown away properly it can be swept away by storms and that go into rivers. The rivers lead into the ocean and then animals can die this is why coral reefs are so fragile.

Thousands of plants and animals depend on each other to survive. All together they make up the coral reefs ecosystem. This includes water, sunlight, and coral polyps and that includes all of the animals and plants living in or near the reef. The animals of the reef help with the growth and the health of the coral reef. For example, some fish help by eating the seaweed that grows on the corals. This can give coral the clean place to grow. Also, the sea anemones and nooks in the rocks help create a safe place for fish to hide if they see a predator coming. Here are 3 places some animals hide. Clownfish stay safe in coral reefs by swimming in or by the sea anemones that sting other animals/predators when they see them coming. Also, a clown fish can swim by a anemones tentacles because they have mucus that cover their body. Some turtles come to reefs and tuck under a ledge to sleep in. Also, moray eels hide in cracks in the coral reefs, and most of the time they stick their heads out to catch fish that swim by. Lots of animals depend on the reefs even predators!
