极致冰原 可爱生灵

几只北极狐正在悠闲的庆祝今天的兄弟姐妹日。这些北极狐住在阿拉斯加附近的俄罗斯北部岛屿弗兰格尔岛上。北极狐幼崽在9周龄时就断奶,但它们享受着来自爸爸和妈妈以及家中其它成年狐狸的保护。当幼崽准备好自己搜寻小的啮齿动物时,成年北极狐会训练它们如何独立生活和保护自己及家人。

几个世纪以来,贵州省的瀑布吸引着陆陆续续的游客。在黄果树国家森林,可以看到壮丽的银链坠潭瀑布,在陡峭的岩石上瀑布细腻流淌,被称为“中国最温柔的瀑布”。如果你喜欢刺激的冒险,你可以步行到黄果树瀑布,远远的你便能听见银链坠潭瀑布那如银铃般的巨大落地声!

聪明的大象

PHP和PostgreSQL的Logo形象都是大象。

非洲象的大脑平均重量约11磅,是陆地动物中最大的。除此之外,它们拥有复杂的大脑皮层,这种特征只在猿、海豚和人类中可见。科学家们认为非洲象之所以智力超群,大脑的构造功不可没,不仅是因为它的尺寸,更是因为不论是野生还是圈养的非洲象,都表现出了高等生物才会有的复杂情绪化行为。
