Why do camels have a thick pad on their chest?

Camels have a thick pad on their chest, known as a chest hump, which serves several purposes. Primarily, it acts as a protective cushion when the camel kneels down, helping to absorb the pressure and prevent injury. Additionally, this pad contains fat that can be metabolized for energy during long journeys through arid environments, allowing camels to conserve water and sustain themselves in harsh conditions.
