Llamas are closely related to camels. Like camels, llamas need very little water to survive which makes them durable for traveling. Llamas became domesticated in 1500’s and have always been valuable work animals. They are mostly used for transportation and packing purposes. A packed llama can travel up to 20 miles in a day. Llamas have unique adaptive feet which allow them to walk on a variety of soils, such as sand snow. Llamas are covered with a thick layer of wool which can grow to be 8 inches long. Their color usually ranges from white to black with shades of brown and gray.
