Pack animals are animals specifically bred or trained to carry loads. Some common examples include:
* Horses: Historically used for transportation, still used in some areas.
* Donkeys: Strong and sure-footed, often used in mountainous regions.
* Mules: A cross between a horse and a donkey, known for their strength and stamina.
* Camels: Adapted to desert environments, used for transporting goods and people.
* Yaks: Found in the Himalayas, used for transporting goods and milk production.
* Llamas: Native to South America, used for carrying loads and wool production.
A single file pack of animals refers to the animals being lined up one behind the other, forming a line or "pack." This is a common way to transport goods on narrow trails or in areas where space is limited.
