text: The camel’s head is a masterpiece of design for a desert-living animal; it has thick bushy eyebrows on projecting bony ridges to shield its eyes from the sun, two sets of extra-long eyelashes and a third eyelid to do the same regarding sand, lots of hair in its small ears to keep the sand out of them, nostrils that trap and retain water vapour in exhaled breath and can close completely against sand, and mouths that have a leathery thick lining that lets them chew the thorniest plants without damage and split lips to make browsing easier.
