Camels can go many weeks without drinking anything at all. The notion that they cache water in their humps is pure myth__heir humps are made of fat, and water is stored in their body tissues. While other mammals draw water from bloodstreams when faced with dehydration, leading to death by volume shock, camels tap the water in their tissues, keeping their blood volume stable.
