Coral Reefs are ecosystem made up of the coral building, their bright and vivid colours can be seen in tropical ocean water around the globe

- Though they make look like colourful plants, coral are in fact made up of tiny animals called Polyps which covered them and support their soft body
- Coral are Mega Builders. Their polyp follicles combine each other resulting in the creation of Colony that acts as a single organism. As they grow over hundreds and thousands of years and finally becomes the Reef
- The largest coral reef is in Australia's great border reef which began growing about 20,000 years ago.
- Though they cover less than 1% of the ocean floor. Coral reef are homes to 25% of all marine creatures
- They provide rich habits that help young fish as they grow. They get their colours from algae or zooxanthellae. Most of their food comes from algae.
- When they become stress by pollution or other factors they evict the algae

Unfortunately, climate changes are putting corals future in dangers along with the millions of species that inhabit reefs and the half-billion people that rely on reef fish for their survival.
