Many mammals survive in deserts by:
being nocturnal. migrating away from deserts during the hot summers. eating cactus. storing water during the rainy seasons.
Many mammals survive in deserts primarily by being nocturnal. This behavior allows them to avoid the extreme heat of the day and be active during the cooler nighttime hours. Other strategies, such as storing water during rainy seasons or having specialized diets, can also play a role, but nocturnality is a key adaptation for many desert mammals.
