Camels are adapted to live in the desert. They have long feet. They live in groups. They have long shaggy coats for harsh winters and shorter coats for summer. They fill their stomach with water which they fill by drinking about thirty gallons in ten minutes. They can survive without drinking water for up to ten months. They store excess food as fat in their hump which they use when food is not easily available. Their mouths are so tough that they can easily eat thorny plants.
