Review: On-Line Coral Reef Course
This new course for divers discusses the coral reef ecosystem and food web. It illustrates its points using animals and plants found in and around coral reefs. For instance, the Caribbean Reef Shark is discussed as a top-level, active, predator. The authors manage to pack loads of information on their example species into a small space, without the prose becoming uninteresting. And even when I thought I knew lots about a subject they managed to surprise me. For instance, did you know that sponges may be able to live to over 1000 years old?
