A camels wide circular feet allow them to walk steadily and easily over the sand. Camels have small bones that stick out of their skulls that act like visors and can keep the sun out for their eyes no matter what time of day it is. Wow, you must be a tough cookie. Ok, here's my last shot. Camels are adjusted to the desert environments soooooo well that even their cells are adapted.
Cells have to maintain water balance through something scientists call osmosis.
What osmosis does is make sure that cells don't take on too much water. If an animal drinks too much, they really have a hard time keeping a balance of water in their cells. Camels, on the other hand, are quite good at it. I think that is quite impressive.
