11. Camel
Camels are uniquely adapted to thrive in the harsh conditions of the desert. Their humps store fat, which can be metabolized into water and energy when resources are scarce. This adaptation allows them to survive for extended periods without food. Additionally, camels can tolerate significant dehydration, losing up to 25% of their body weight without severe effects, a feat that would be fatal to most other mammals. They can also endure body temperatures that would cause heatstroke in humans. These remarkable adaptations enable camels to navigate and survive in some of the most extreme environments on Earth.
