Animals that can live longer without water than camels

Camels are known to live without water for many weeks in the desert. But it has been found that giraffes and kangaroo rats can live for more days than the camels. Giraffes eat food high in water content, and so they can live without water for weeks. Kangaroo rats never drink water but metabolise water from the seeds they eat.
