俨然好奇心双语看世界

小猪会做家务吗

鲸鱼会用泡泡捕鱼吗

大树会流血吗

大自然无奇不有

让我们行动起来

一探究竟

夜色将近

小朋友们都已在爸爸妈妈的陪伴下进入梦乡

但在此时

有一些小动物们可没有睡觉

他们拥有一个我们人类十分羡慕的本领

那就是在黑暗中也能看清周围的世界

动物的眼睛越大

吸收的光线就越多

视力也就越好

眼镜头就是这样

他们的眼睛又大又圆

十分可爱

黑暗中的捕食者猫头鹰也具有强大的夜视能力

他们的视力是人类的十倍

除此之外

大眼睛的章鱼

长着w形状瞳孔的墨鱼

拥有狭长瞳孔的鳄鱼和猫科动物

都可以在光线微弱的地方发现猎物

虽然我们人类并没有获得与生俱来的夜视能力

但科学家们一直都在研究那些夜视能力很强的动物

说不定在未来的某一天

我们可以借助科技的力量

在黑暗中看清一切呢
