The document discusses the adaptations that camels have developed to survive in the desert. It lists several structural adaptations including thick eyelashes to protect from sand and sun, nostrils that can close to keep out blowing sand, fat stored in humps to survive without food or water for long periods, thick fur and underwool for warmth and insulation from heat and cold, thick leathery pads on their knees to prevent burns from hot sand, long strong legs to carry heavy loads over long distances while keeping their body off the hot sand, and broad flat pads on their hooves that spread out to prevent sinking in sand.
