This Is Where Camels Store Their Water
Camels have special blood that allows them not to sweat.
If you watch a camel, you may be tempted to believe that they store water somewhere, perhaps in their bumps. In actuality, camels are just very good at retaining the water they do have, surviving with very little and refilling near-instantly when possible.
These animals can down over more than 100 liters of water in a few minutes. However, this level of sudden hydration would mean game-over for many animals but camels aren't actually over-hydrating, they're just restoring what they lost.
Normally that kind of quick drinking would kill most other animals by diluting their blood. But camels can hold a large amount of water in their first stomach, or rumen. The rumen lets all the water into the blood slowly over several hours.
Camels also have special blood cells, small and oval-shaped, that allow them to flow through veins much better, even when the heat tightens them up. So even when camels are running low on water, they don't have a problem functioning.
This is also why camels don't sweat easily, they almost never lose water. This also helps them conserve energy.
Finally, camels have super water-efficient kidneys and large intestines so they lose very little water through their excretions. Are you impressed yet? Watch this video by SciShow to find out all you need to know about camels and hydration.
