Addax
The Addax is a critically endangered antelope that lives in the Sahara Desert. It can survive without drinking water and changes its coat color with the seasons.
What is it?
The Addax (Addax nasomaculatus) is a type of antelope adapted to extreme dry environments. It can live with very little water, getting most of its moisture from the plants it eats. Its coat changes color: white in summer to reflect sunlight, and grayish in winter to absorb heat.
Who used it?
People have hunted the Addax for its meat and hide. Overhunting and habitat loss have made it critically endangered. Today, conservation programs in zoos help protect it.
When and where?
The Addax lives in the Sahara Desert, mainly in eastern Niger, western Chad, and possibly southern Algeria. It was once found across North Africa, but now only small populations remain.
What does it tell us?
The Addax shows how animals can adapt to harsh environments. Its seasonal color change and ability to go without water are amazing adaptations. But it also tells us that human activities can push species to the edge of extinction.
Compared to today
Unlike many animals that need daily water, the Addax can survive for weeks without drinking. Its desert adaptations are similar to camels, but it is more specialized for sandy deserts.

白羚
白羚是一种生活在撒哈拉沙漠的极危羚羊。它可以在不喝水的情况下生存，并且毛色随季节变化。
这是什么？
白羚（Addax nasomaculatus）是一种适应极端干燥环境的羚羊。它可以在几乎没有水的情况下生存，主要从吃的植物中获取水分。它的毛色会变化：夏天是白色以反射阳光，冬天是灰色以吸收热量。
谁使用它？
人们曾为了肉和皮而猎杀白羚。过度捕猎和栖息地丧失使其成为极危物种。如今，动物园的保护项目帮助保护它。
何时何地？
白羚生活在撒哈拉沙漠，主要分布在尼日尔东部、乍得西部，可能还有阿尔及利亚南部。它曾经遍布北非，但现在只剩下少量种群。
它告诉我们什么？
白羚展示了动物如何适应恶劣环境。它的季节性毛色变化和无需饮水的能力是惊人的适应。但它也告诉我们，人类活动可以将物种推向灭绝的边缘。
与今天相比
与许多需要每天喝水的动物不同，白羚可以数周不饮水。它的沙漠适应类似于骆驼，但更专门适应沙质沙漠。
