Africa's might and grandeur is formidable. Here, two powerful empires co-exist, one of land and one of the water realm. For most of the year these two entities work peaceably side by side, but in the dry season the rules change. The dry season is predator prime-time. The shore of the Luangwa River, Zambia, is the boundary between kingdoms and during this time, the battle begins. It's risky business for a lion to go up against a crocodile. But here, it's the ultimate conflict. Some of nature's most powerful jaws lock in confrontation as the world's fiercest predators battle for supremacy.—Christo Ras
