Learn from the Experts

There are so many things to learn about corals! Why are some corals so colorful? What kind of animals live on corals? What do corals and geology have in common? Coral scientists and experts will answer your questions below! You can continue exploring and learning from coral experts here.

Coral Careers

Are you interested in working with corals? From traveling the world to protecting vulnerable species, learn what it takes to work in coral science. You can explore other coral careers through NOAA here.

Think About It

  1. What would the ocean look like without corals? Why are corals an important part of the ocean ecosystem?
  2. What conditions are needed for a coral to grow?
  3. If you were to study corals, what would you want to research and how would you do it?

You and Your Student

  • Design a deep-sea coral food web (below 500 meters) with the animals typically found at depth. How does each species utilize the coral? Then take one of the organisms away. How do you think the ecosystem will be affected? 
  • List and describe the reproduction options in corals. What advantages and adaptations have corals developed to reproduce? 
  • Describe the life cycle of a coral mound over two different time scales – twenty years and a thousand years. What changes could you see in the short term (twenty years)? What changes could occur over a thousand years and how would the coral mound ecosystem change during that time?

For Teachers
