　　An arctic fox pup awakens from a nap on the summer-greened Canadian tundra.
　　Most arctic foxes turn white in winter to blend with their snowy surroundings, though some, called blue foxes, wear a brownish-blue coat. These delicate-looking mammals have adapted a host of physical attributes- short ears; a short muzzle; thick fur - to help them bear up under some of Earth’s harshest living conditions.

　　在夏天青郁的加拿大苔原上，一头小北极狐刚从小憩中醒来。大多数北极狐将在冬天变成白色，以适应周围的雪地环境。有些则换上青褐色的外衣，称为蓝狐。这些看似娇弱的动物们拥有适合生存的身体特征，如短耳，短鼻，厚毛等，这些可以帮助它们承受一些地球上最恶劣的生存条件。
