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 to find food and stay alive. The reef is also host to numerous examples of symbiosis and finding food and safety in the strangest of places, whether that be in a shark’s mouth or ‘vacuuming’ the sandy seabed. In this lesson, students are challenged to create the ultimate reef organism.
