Elephants have several physiological adaptations that enable them to thrive in arid environments. Some of these adaptations include their ability to store and conserve water in their bodies, their efficient cooling mechanisms such as large ears that help dissipate heat, and their ability to go for long periods without water by relying on moisture from plants and food sources. Additionally, elephants can also dig for water sources in dry riverbeds and use their strong sense of smell to locate water underground.
