There is plenty of food in the Pacific Ocean, but it is the challenge of finding that food that drives all life in the Pacific. In the voracious Pacific we meet a destructive army of mouths, a killer with a hundred mouths and the biggest mouth in the ocean.
Explore the wild blue Caribbean waters of Cozumel, a lush paradise packed with marine surprises. From the spectacular Paso Del Cedral coral reef to the world's longest subterranean underwater cave system, go where only the bravest divers dare venture.
Sixty-six million years ago, an asteroid wiped out the dinosaurs in a fiery global catastrophe. But we know little about how their successors, the mammals, recovered and took over the world. Now, hidden inside ordinary-looking rocks, an astonishing trove of fossils reveals a dramatic new picture of how rat-sized creatures ballooned in size and began to evolve into the vast array of species.
On a high ridge in Newfoundland, Canada, nestled between the Atlantic Ocean and the borders of an old grove forest, a Red fox, the matron of her family group, gives birth yet again. Follow the pups as they grow and learn to hunt, adapt, and survive. Explore the family dynamic of these clever creatures as bonds are formed. But the vixen knows that not all her cubs will inherit these tall trees, crystal lakes, and the ocean spray. Before the snows come again, she will have to banish some of her offspring for the good of the family. We also hear from scientists in Madison, Wisconsin and Bristol, England, about their studies on urban Red foxes who are facing a much different challenge than their Canadian counterparts. And another scientist tracks how Red foxes are moving out to the Arctic tundra and surviving in one of the harshest landscapes.
