Travel to Ankarana, a nature reserve in Madagascar that puts the "wild" in wilderness.

The remote Ankarana preserve on the island of Madagascar, a few hundred miles off the coast of Africa, shelters an astonishing array of exotic wild animals. Protected by a fortress of ancient coral mountains with forbidding razor-sharp spires, some of these unusual creatures have thrived unscathed and unchanged for thousands of years. Aggressive Nile crocodiles, incredibly rare crowned lemurs, countless chameleons, and the lethal fossa, described as a ''mongoose on steroids,'' share the lush forests and deep, forbidding caves of Ankarana.

In Ankarana, strange sights and puzzling biological mysteries abound, and noted wildlife experts and top biologists are your guides as NOVA brings you an exclusive insider’s look at this rarely seen corner of the world. Find out why normally sun-loving crocodiles lurk in cool, dark caves. See how the hyena-like fossa leaps from branch to branch as it rules its jungle habitat. And join the Ankarana locals and discover how they co-exist alongside animals that sometimes hunt humans.

Explore Secrets of the Crocodile Caves and discover some of the most unusual creatures ever to evolve on earth.
