Nothing in the Okavango makes more noise about its territory than a hippo, and nothing demonstrates it better than two bulls squaring up jaw to jaw in open water — a dominance display that looks like violence and mostly isn't, though it can turn into exactly that if neither one backs down.
The quieter version of the same behavior: a single animal, side-on, gape held wide enough to show the full span of the jaw. Less drama than the two-animal clash, but a cleaner read on the sheer scale of the thing.
And the largest land mammal on the continent, doing the most ordinary thing an elephant does — drinking, front-on, with the whole animal doubled in the water's reflection. Water dependency isn't an abstract ecological concept out here; it's the organizing fact of the whole Delta, and every giant in it is built around being near enough to a permanent supply.
