why do camels have humps

Camels have humps to store fat, not water as is commonly believed. The fat stored in the humps can be used as a source of energy and sustenance when food and water are scarce, allowing the camel to survive in harsh desert environments. The humps also help regulate body temperature by keeping the camel's core body temperature stable in extreme heat.
