The largest reptile on earth—the saltwater crocodile—is lurking in the rivers of Australia's Northern Territory. A master predator, each year this cunning croc is tested by nature's harsh extremes and must battle for dominance with its own kind.

Using high-speed cameras and infrared technology, National Geographic reveals how this stealthy "salty," with senses and instincts honed over the ages, is able to retain King Croc status.

How our DVDs and DVD-Rs Differ

Customers who purchase programs in the NG DVD-R 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-R titles are not closed-captioned. We apologize for any inconvenience this limitation may cause.
