Nature's ugliest creatures are spotlighted, including the dung beetle, elephant-seal bull, ghost-faced bat, Indian stork, naked mole rat, needle-toothed viperfish, proboscis monkey, star-nosed mole, tapeworm, vulture and warthog. Included: how their looks and attributes contribute to their survival.

5The Desert Lions

Dr. Philip Stander, a Namibian carnivore expert, investigates the resurgent lion population in the Namib Desert. Included: the uniqueness of the big cats; and their biggest challenge---residents who see them as threats to livestock.

6Parrots in the Land of Oz

53 minJan 27, 2008

An exploration of Australia's diverse parrot population, including the fig parrot, the golden-shouldered parrot and the palm cockatoo. The overview examines their mating rituals and fight for survival, and details the damage the birds can do to farmers' crops.

7Crash: a Tale of Two Species

53 minFeb 10, 2008

The link between the horseshoe crab, which has remained the same for some 350 million years, and the red-knot shorebird, is explored. The horseshoe crab's spawning grounds, the Delaware Bay, are an important feeding ground for the red knots on their way from Tierra del Fuego to the Arctic. Included: how biologists connected a drop in the red-knot population to a similar decrease in the crabs. Also: how horseshoe-crab blood is used to test human medicines.

8Arctic Bears

53 minFeb 17, 2008

An examination of what the future may hold for polar bears, which evolved from grizzlies during the last ice age, due to the dramatic changes in their Arctic habitat. The documentary also details how grizzlies are expanding their territory northward, encroaching upon the polar bears' domain. Included: a polar bear giving birth; grizzly and polar-bear mothers teaching their cubs to hunt.

9What Females Want and Males Will Do (1)

53 minApr 6, 2008

In the animal world females often call the shots. But their decisions may be surprising. In an effort to understand the mating game, NATURE follows biologist Chadden Hunter, PhD, through the Simien Mountains of northern Ethiopia, as he observes a troop of geladas, close cousins of baboons. He found that in gelada society females make all the decisions about mating, even though males are twice their size. The males are evaluated on everything from body heat to baby sitting skills. And once selected, no male gelada can ever rest on his laurels. Another male is always auditioning for his job. You’ll also see female barn swallows that choose a male by the color of his chest and encounter a robotic sage grouse that is helping researchers learn about this species’ elaborate courtship displays.

10What Females Want and Males Will Do (2)

53 minApr 13, 2008

Apparently, there is nothing a male will not do for the right to mate with a female — dance, sing, fight, change body colors, illuminate, even agree to be eaten alive. There is often a surplus of males, and they are instinctively driven to compete in order to pass their genes to the next generation. But it takes two to tango. Now, scientists are learning to what extremes males will go in order to find that dance partner.

11The Gorilla King

53 minApr 20, 2008

A fascinating profile of a 33-year-old silverback named Titus, the leader of a gorilla clan in the mountainous region between Rwanda and Congo who faces a challenge for supremacy from his second-in-command, Kuryama. Archival footage and the observations of researchers fill in his backstory, including how, as a young adult, he engaged in secret liaisons with females behind the back of pack leader Beetsme, then led a rare bloodless coup against Beetsme.

12Superfish

53 minMay 4, 2008

Marine biologist-filmmaker Rick Rosenthal documents billfish (marlins, sailfish and swordfish), whose numbers have dwindled over the past 50 years from overfishing. Included: off Mexico's Contoy Island, he finds thousands of sailfish feasting on sardines; and along Australia's Great Barrier Reef, he swims with a "grander" (a marlin over 1000 pounds).
