The waters around Isla Holbox off Mexicos Yucatán Peninsula teem with plankton, a feast for giant whale sharks—10-meter giants that gather by the hundreds from June through September. These super-sized, but toothless filter feeders are the core of a local tourism industry, but over-development could threaten this delicate balance. Dr. Sylvia Earle narrates. Kip Evans - Producer and Director of Photography. 2010 Blue Ocean Film Festival non-broadcast winning Film.
