Leopards are considered to be extremely shy big cats. Only a few animals can match the elegance of these feline predators. The cautious hunters are rarely seen in the wild for more than a few seconds. The cats can be observed more extensively when they rest asleep in a tree and recover from the mostly nocturnal hunt. But a leopardess has switched to hunting in broad daylight. Its home along the brook bed of the Olare Orok offers everything a mother needs to protect and nourish its offspring: picturesque rocks and dense bush, a landscape in which the big cat can disappear in seconds to sneak up on potential prey, which includes warthogs and antelopes. But hyenas and lions are always ready to contest for its territory and nourishment. The renowned wildlife filmmaker Reinhard Radke managed to capture astonishing insights into the social life and hunting tactics of the ambush hunters in the Maasai Mara.

Cuba's enforced isolation has resulted in the unlikeliest of marine reserves: a huge, rambling archipelago known as Jardines de la Reina, or "Gardens of the Queen." Stretching around 140 miles along the southern coast of Cuba, it's one of the longest barrier reef systems in the world. Get an up-close look at Fidel Castro's diving playground, a forgotten ocean paradise unseen for half a century, and witness exotic species rarely seen elsewhere in the region. It's the lost jewel of the Caribbean, but how long can this pristine wilderness survive?

A dramatized tale of how wolves recovered in Europe after almost going extinct.

As co-created by environmentalists Stephan Poulle and Nicolas Koutsikas, the documentary Gulf Stream and the Next Ice Age argues and provides evidence for the idea that mankind is wreaking permanent and potentially irreversible damage on the ecosystem by interfering with the natural course of the Gulf Stream. Koutsikas and Poulle suggest that this interference, in turn, will prompt a new Ice Age that virtually destroys the modern world.

Computer-generated imagery and other visualization techniques reveal how it would look if all the water was removed from RMS Titanic's final resting place.

Coral biologists are concerned about the genetic health of many endangered coral. This short film follows a team of Smithsonian scientists as they attempt to use cryopreserved coral sperm to introduce DNA to new populations of elkhorn coral. If this technique works, it could have lasting impacts on how we are able to protect and restore endangered coral species from near extinction.
