Deserts are such an interesting biome. The lack of vegetation is a big factor in it's look. 
I agree, the sands are so beautiful, but one could experience a big problem if they can't find shade due to lack of vegetation and water sources.
Yes indeed. It's interesting that animals still manage to live in those conditions while the barren area makes it difficult. 
Especially camels! I think I read that they store water in their humps, but I'm not sure how long they can go without water.
Yea those are very peculiar animals. There are only three surviving species.
