PLANET EARTH From Pole to Pole

Nowhere on our planet Earth is the life giving power of water so clearly demonstrated. The Okavango becomes crisscrossed with trails as animals move into its heart. The new arrivals open up paths like arteries along which water flows, extending the reach of the flood. This is an Africa rarely seen - a lush water world. Some creatures are completely at home here. These are lechwe（赤列羚） - antelope（羚羊） with hooves（蹄子，复数形式，单数是hoof） that splay widely, enabling them to move its speed through the water.



For others the change is far less welcome. Baboons are somewhat apprehensive bathers. The water brings a season of plenty for all animals. Hunting dogs. These are now among the rarest of Africa's mammals, but then nonetheless the continent's most efficient predators.



Their secret is teamwork. Impala（黑斑羚） are their favorite prey. They start to hunt and the pack splits up. An aerial viewpoint gives a new insight into their strategy. As the dogs approach their prey they peel off（离群） to take up separate positions around their target. They seem to form a cordon around the impala.
