The Great Barrier Reef stretches for over 2,300 kilometres along the eastern coast of Australia, but the creatures that have created this habitat can measure just a few millimetres across. This lesson covers the basic anatomy of the coral polyp, their life cycle and reproductive processes, and finishes with a game that shows how tropical coral polyps get their energy boost to create such amazing structures.
