What do the antelopes living in the desert drink?

Many antelopes, such as the White Oryx found in the Arabian Peninsula, have adapted themselves to a life in the desert. They do not drink water, but eat when it is cooler and when the plants are wet with dewdrops. They pass very little moisture out of their bodies because their bodies have a system of cooling the blood before it reaches the brain. Their fur is generally paler on their underside to reflect ground heat away from the stomach. Even humans such as the San people living in the Kalahari in South Africa have adapted themselves to the desert life. They are experts at finding juicy melons and water storing roots. They also bury sealed ostrich eggs filled with water for use during dry seasons.
