How does a coral reef grow?

Corals are tiny animals that make skeletons big enough to be seen from space. This short and simple video shows how an entire reef is built using the example of a coffee cup, juice cup and plumeria flower.

Stanford University marine biologist Dr Steve Palumbi makes it easy to understand how important reefs are as ecosystems – not just for fish but for the original inhabitants, tiny coral polyps that help create the amazing colour and structure of the reef.
