horses
Explanation:
In the caravan success, camels and horses were a vital part.
The camel was one of the most important of a caravan. Without these animals, trades that were carried out across the Sahara couldn't have been possible.
Caravans are actually group of travelers, who can be traders and who move their goods across long distances like the Sahara.
Animals like camels and horses made the caravan success because these animals can actually go long distance travels without water. They are adapted to survive in deserts and wilderness.
For example, the camel can survive changes in body temperature and withstand the heat of the day and the night cold experienced in the deserts.
