两只饥饿的小海狸(Two hungry baby beavers)

看这只凶猛的海狸，大自然的工程师。他们用巨大的橙色门牙砍树，用它的碎片建造了两个主要结构：大坝和小屋。海狸利用小屋躲避捕食者，储存食物，休息，并保护它们的后代。入口建在较低的水平面上，因此当海狸在下游建造水坝时，会部分淹没小屋，增加额外的保护元素。这种水下进入对海狸来说没有问题，因为它们可以屏住呼吸长达15分钟。它们的桨状尾巴帮助它们游泳，当捕食者出现时，它们也会用它拍打水面或地面来警告其他海狸。

Behold the mighty beaver, nature’s engineer. They fell trees with their massive orange incisors, using pieces of it to build two main structures: the dam and the lodge. A beaver uses a lodge to hide from predators, store food, rest, and protect their offspring. The entrance is built at a low level so that when beavers construct a dam downstream, it partially floods the lodge - adding an extra element of protection. This underwater entry is no problem for beavers, as they can hold their breath for up to 15 minutes. Their paddle-shaped tail helps them swim, and they also use it to slap the water’s surface or the ground to warn other beavers when predators appear.
