Coral Reefs

Science · Ocean Life · conceptual

Know that coral reefs are built by tiny living animals called coral polyps, that reefs are home to more species than almost any other ocean habitat, and that they are sometimes called the 'rainforests of the sea'

What mastery looks like

  • State that coral is built by tiny living animals called polyps, not made of rock
  • Describe coral reefs as one of the most biodiverse habitats in the ocean
  • Explain why reefs are compared to rainforests

Check your understanding

If Coral Reefs watched a documentary about coral reefs, could they explain that coral is actually made by tiny living animals, and that reefs are home to an incredible number of different species?
