...camel

There are so many "special features" on the camel! His feet are spongy and spread out as he takes a step, so that he won't sink in the sand! His long eyelashes keep flying sand out of sensitive eyes, but if that doesn't work he has a third eyelid that's transparent so that he can see and still keep his eyes sand-free. He has very good hearing and can close his nostrils. During mating, the male camel uses a fleshy frog-like inflatable soft palate to attract the female. They have thick skin on their backs to protect them from the sun, but thin skin on their bellies to help keep them cool. Large callused areas keep their knees safe from the burning sand.
