How much do you know about animal superpowers? Follow the everyday lives of prairie dogs, howler monkeys, and rattlesnakes, as they harness the power of sound to protect themselves.
For many endangered baby animals, the right zoo can mean hope for the entire species. Watch an endangered red panda cub get a warm welcome at Cornwall's Newquay Zoo, a rare baby macaque receive care from parents and keepers alike at the Dudley Zoological Gardens, and more.
When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.
Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.
In the Gulf of Oman, survival is all about defense. Some species of sea urchins and sea slugs rely on toxins to keep predators at bay, while guitarfish use their size and armored bodies to stay off the menu. Peek into a little-known reef where fortune favors the bold and the well-prepared.
At the very northern edge of North America is Ellesmere Island, where the unforgiving Arctic winds tear through the tundra, dipping temperatures to 40 below zero. Running through this shifting sea of snow and ice is one of the most hardened predators on the planet, the White Wolf. But as the spring melt approaches, these roaming hunters must adapt to being tethered parents as new additions to the pack have just been born. With their herds of prey continuing to move, we witness a desperate race to keep up and bring back a kill to the hungry mothers and cubs. Traveling farther and farther away from their den each day puts these hunters and their children at risk in this fight for survival.
