Planet Earth DVD Episode Guide - Episode 3 - Fresh Water


The 3rd installment in the Planet Earth series describes the diverse courses taken by rivers and the species that live within them. Though only 3% of the world’s water is fresh, all life ultimately depends on it. The journey of episode 3 begins with a tropical downpour onto Venezuela’s Tepui mountains, with the water culminating into streams. Hundreds of miles later, the streams form a rapidly flowing river. To illustrate the beauty of rapids, Planet Earth episode 3 showcases Angel Falls, the world’s highest free-flowing waterfall. The water of Angel Falls drops nearly 1000 meters and is mostly blown away before ever reaching the bottom.

Flowing water causes natural erosion, illustrated in Planet Earth with images of the majestic beauty of the Grand Canyon, created by the Colorado River over the course of 5 million years. Across the globe, in Japan, water is home to the biggest amphibian, the giant salamander, which can grow to two meters in length. Also at home in the water, salmon embark on the largest freshwater migration, enduring the treachery of the river and hunted by grizzle bears.

Also featured are smooth-coated otters, repelling mugger crocodiles as they swim. Closely related to the mugger crocodile, nile crocodiles are shown ambushing wildebeest as they attempt to cross the Mara River. Roseate spoonbills are numerous in the Pantanal and are prey to spectacled cairman. Also shown are cichlids, piranhas in a feeding frenzy, river dolphins and swimming crab-eating macaques.

Planet Earth DVD Episode Guide - Episode 4 - Caves

Episode 4 of the Planet Earth DVD series explores the Earth’s caves and tunnels; the “final frontier” of our world. The Earth’s biggest cave, the Cave of Swallows in Mexico, with a depth of 400 meters, is featured in this episode. Also featured is Deer Cave in Borneo, inhabited by three million wrinkle-lipped bats which live on the cave’s ceiling. The bats deposit guano onto an enormous mound on the floor of the cave. The mound is 100 meters high and is blanketed with feeding cockroaches. Planet Earth also offers a glimpse of other cave life, including a number of subterranean, eyeless creatures, such as the Texan cave salamander and a species of crab. The episode closes with beautiful footage of the Lechuguilla Cave which was only recently discovered. Footage of Lechuguilla Cave includes the ornate gypsum crystal formations, carved by sulphuric acid, found within the cave. Watch: Planet Earth - Caves Post adapted from Wikipedia.

Planet Earth DVD Episode Guide - Episode 7 - Great Plains

Step out onto the Savanna, steppe, tundra and prairie as episode seven of the Planet Earth DVD series looks at the resilience of grasses in treeless ecosystems. The vast grasslands on earth contain the largest concentrations of animal life. In outer Mongolia, a herd of gazelle is shown fleeing a bush fire and are forced to graze in other areas. Fortunately, grass can repair itself rapidly and the burned area soon recovers from the fire damage. Out on the Artic tundra, millions of migratory snow geese arrive to breed. Their young are heavily preyed on by the local Artic foxes. Meanwhile, time-lapse photography is used to depict the movement of a caribou herd as a young calf is killed by a wolf. South of the Artic, on the North American prairies, bison engage in the ritual of determining who is the dominant male. Far away on a Tibetan plateau, the highest plains in the world are home to the yak and wild ass, even though there is little grass that grows. The most numerous resident on...

Planet Earth DVD Episode Guide - Episode 2 - Mountains

The second episode of the Planet Earth DVD set focuses on the Earth’s many mountains. Extensive aerial photography was used by the show’s creators to explore all the main ranges. Ethiopia’s Erta Ale, the longest erupting volcano (for over 100 years) in the world is among the mountains shown. Nearby in the highlands, geladas, the only primate whose diet consists almost entirely of grass, are shown inhabiting the slopes nearly 3 miles up. The most numerous of their kind, the Geladas troop numbers 800 members. Contrasted with the numbers of Geladas is the critically endangered Walia Ibex, which lives alongside them. Both the Geladas and the Ibex must be on a constant lookout for the predatory Ethiopian wolves which share the area. Far away in the Andes, which have the most volatile weather on earth, Guanacos are shown enduring a flash blizzard, a plight shared by a group of puma. Filming the normally solitary Puma in a group was one of the large accomplishments of the Planet Earth ser...
