Elephant

African elephant Shani and her spirited son Jomo set out on an epic journey with their herd, traveling hundreds of miles across the vast Kalahari Desert, from the Okavango delta to the Zambezi River, just as countless generations of their ancestors have done before. Shani and her family are among the last elephants on earth to make these lengthy migrations. She's mother to wide-eyed, one-year-old Jomo, who has yet to experience a migration, and at 40 years old, she is next in line as herd matriarch, a position currently held by her older sister Gaia. Gaia's herd is among countless species - from hippopotamus to lechwe to baboons - that rely upon the life-giving water that flows from the mountains and transforms the heart of the desert into a green oasis known as the Okavango delta. But the season's end is near and soon there will be a mass exodus. Nothing on Earth is more precious to life than water. And perhaps nowhere is this more apparent than the Kalahari desert in southern Africa,
