Firstly I want to recommend Stephen Budiansky's excellent The Nature of Horses to anyone, and everyone. It's a great book, interesting not just to horse-lovers but to anyone who's interested in the way animals work and think. It covers a lot of ground about evolution, physiology and animal behaviour.

Secondly, I want to know if anyone knows of a similar book covering Camels? Or just a really good book about camels?
