Deserts are places of extreme weather. With less than 16 inches of rainfall a year, deserts are dry environments with strong winds, scorching heat during the day and freezing temperatures at night. Despite these conditions, animals have adapted to live within this harsh landscape. Some animals can go their entire lives without drinking water; instead they get it from plants or animals they eat. To survive the heat of the day, many smaller animals stay in underground burrows, where it is much cooler, and will come out during the night.
