Pictures of beautiful corals

We found these pictures of coral reefs on the Internet. It is really amazing to see so many colourful corals! There are so many different types of corals as shown below in the pictures! Some of them look like our fingers sticking out. It is quite funny isn't it?

We can see from the pictures that a lot of fishes are attracted and dependent on coral reefs! So we must do our part in saving the coral reefs from being destroyed!
