Different species have adapted to life on the coral reef in amazing and diverse ways. From sleeping in mucus bubbles, to flexible snakelike skeletons, life on the reef has had to find ingenious methods for finding food and staying alive. The reef is also host to numerous examples of symbiosis, and creatures finding food and safety in the strangest of places – whether in a shark’s mouth or by ‘vacuuming’ the sandy seabed. In this lesson, students are challenged to create the ultimate reef animal.
