Hammerheads school in enormous numbers. Coral reefs ripple with color by day but at night turn into killing grounds for packs of whitetip sharks. Pristine waters brim with tuna and dolphins in hot pursuit of clouds of fish. Isla del Coco, or Cocos Island, appears as a tiny dot on a map in the Pacific Ocean more than 300 miles off the coast of Costa Rica, and is home to one of the greatest concentrations of predators on the planet. Dive into this carnivorous crowd in Shark Island with marine ecologist Enric Sala and an international team of explorers and scientists. The team traverses hundreds of square miles of ocean in search of clues to explain why so many predators congregate here and why, just outside Cocos' protected waters, life largely disappears.

How our DVDs and DVD-Rs Differ
Customers who purchase programs in the NG DVD Exclusives Library will receive a non-interactive, play only disc. There is no chaptering information on these DVDs, but there are chapter marks approximately every five minutes, which make it easy to fast forward through a program. The DVD-R format provides the digital video and audio quality you expect from all of our DVDs.
NOTE: The NG DVD Exclusives titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
