Africa - Kalahari

Deserts, like southern Africa's Kalahari and Namib, are strange and by definition are particularly dangerous and demanding environments, requiring elaborate adaptations. Some are behavioral, like tricks to steal food or even lay eggs in live hosts. other are anatomical. All the more precious is the rare water, so drinking pools are crucial for carnivores and preys. Astonishingly, vast quantities are trapped in huge cave systems underground, where aquatic life is scarce due to little food and light dripping in.
