Coral Reef

What is Coral Reef?

Coral reefs create diverse underwater ecosystems as coral polyps build them by secreting calcium carbonate. These reefs thrive in shallow, warm waters and support a wide variety of marine life. They provide food, shelter, and breeding grounds for countless species, making them one of Earth’s most biodiverse habitats.


Underwater Cities

A coral reef is like an underwater city made up of tiny animals called corals. These corals build hard, rock-like structures where many ocean creatures live. Coral reefs are some of the most colorful and diverse places in the ocean, full of fish, sea turtles, and other marine animals.


How Coral Reefs Form

Coral reefs are made by tiny animals called coral polyps. These polyps live together in huge groups and build hard shells made of calcium. Over time, their shells pile up to create a reef. Coral reefs grow in warm, shallow waters where sunlight can reach because they need sunlight to survive.


Why Coral Reefs Are Important

Coral reefs are like nurseries for the ocean. Many fish and other sea creatures start their lives here because reefs provide food and shelter. Coral reefs also protect coastlines from strong waves and storms and support the fishing and tourism industries that many people depend on.


Animals in Coral Reefs

  • Fish: Clownfish, parrotfish, and groupers live in reefs.
  • Invertebrates: Crabs, shrimp, and sea urchins hide in the coral.
  • Other Creatures: Sea turtles and eels often visit coral reefs.
    These animals make coral reefs some of the busiest ecosystems on Earth.

Affects on Humans

Coral reefs help produce the oxygen we breathe and provide food, like fish and shellfish, for billions of people. They’re also beautiful places for snorkeling and diving, attracting visitors from around the world.


Threats to Coral Reefs

Coral reefs are in danger because of pollution, overfishing, and climate change. Rising ocean temperatures can cause coral bleaching, which harms the corals and the animals that live there. Protecting coral reefs is important for keeping the ocean healthy.
