        Whale Sharks

        Reaching fifty feet long, the whale shark grows larger than a school bus, but are completely harmless since they eat only plankton and small fish.  The local economy of Holbox Island is supported by the ecotourism generated as visitors come to this tiny island to swim with the whale sharks. The accompanying lesson discusses types of plankton, their importance in ocean ecosystems, and methods of studying plankton.
