Nature: Invasion of the Killer Whales (8 pm)
A shift of power is taking place at the top of the world. The Arctic is undergoing a dramatic change, and with this change one iconic Arctic hunter may soon have to give way to another as solid ice turns to open sea. The polar bear, once king of the North, needs ice to stalk its prey. Killer whales, or orca, on the other hand, are unable to hunt in an ocean locked in ice. As the ice increasingly disappears, the tables have turned. Polar bears are struggling to survive while the now open ocean provides bountiful new hunting grounds for the whales.
Sex in the Wild (9 pm)
Sex in the Wild takes viewers from the Okavango Delta in Botswana to the Australian Outback, and from a Borneo rainforest to the waters of New Zealand, to study animal reproduction in vivid detail.
Veterinary scientist Mark Evans and anatomist Dr. Joy S. Reidenberg, experts in animal biology, reveal the natural mating, birth and rearing behaviors of elephants, kangaroos, dolphins and orangutans, all while capturing rare, beautiful footage of these species in their natural habitats. The series brings viewers a deep level of detail about these species’ mating methods and reproductive anatomies, and illustrates how scientists help preserve certain species for future generations, both in the wild and in a laboratory setting.
Episodes depict how animals woo the opposite sex, mate, and raise their young in extreme environments. The series highlights conservation and preservation efforts to protect endangered species, and explores growing attempts to safely control increasing populations of particular species, such as Botswana’s elephants.
