Sure, but not very often. Their humps provide them with enough energy for up to seven months in the winter (but less than a week in the peak heat of the summer). You can tell when a camel needs to wet its whistle by the size of its hump, which actually shrinks as the camel uses up its stored fat.
Camels are just very efficient at using water, and they’re well-adapted for dehydration. The camel seems to be designed – both inside and out – to hold on to whatever water it takes in. Its fur prevents the camel from sweating too much. Its blood cells are also tiny enough to keep circulating as the camel’s blood thickens from dehydration – but elastic enough to hold lots of water. If a thirsty camel finds an oasis, its red blood cells might balloon to more than twice their size – while its hump remains unchanged.
