(Dive Travel Business News - August 11, 2010) -- International Whale Shark Day is August 30, 2010.

The congregation of so many animals is unusual. Holbox Island is unique in that it is located where the Caribbean Sea and the Gulf of Mexico join. There are upwellings of nutrient rich water that feed the food chain that contains everything from the tiniest plankton to schools of fish, sea birds, flamingos and ibis and of course, the giant yet vulnerable whale shark. It is truly a special place.
Holbox Island is only the second instance where marine scientists have discovered whale sharks are feeding on not just plankton but also fish eggs that are suspended in the upwellings.
