Welcome to Aria and Alan's open class!
This is lesson 3: Camouflage.
Hi audience,
Did you know that chameleons are famous for camouflage? They can change their skin color depending on their environment.
Camouflage is that animals use their look to fool their predator or prey. There are 3 types of Camouflage.
- Disguise or concealing coloration. The object uses this strategy to blend into the background. For instance, the walking stick living in trees disguises itself as a stick. And the snowy owl is perfectly concealed by its feathers which look like snow.
- Mimicry is when an animal looks like some other dangerous animal to scare away its predator. One good example is that the non toxic scarlet king snake has colors and patterns similar to the toxic coral snake.
- Disruptive coloration is used by animals like zebras, which live in a herd and have features like spots and stripes so each one doesn’t stand out.
Plants can Camouflage too! Let’s take a look at the Venus flytrap. At regular times, the Venus flytrap has its leaves open, with a red color on the surface of the leaves, looking like a flower in bloom. After attracting a bug to come by, it will quickly close the leaves and trap the bug.
Soldiers dress themselves in colors of nature to protect themselves from enemies, and Alan loves to camouflage in blankets and even pillows to hide from me! Thank you for watching! Hope you enjoyed it!
大家好，
您知道变色龙以伪装闻名吗？它们可以根据环境改变肤色。
伪装是指动物利用它们的外观来欺骗掠食者或猎物。伪装分为3种类型。 1.拟态或掩饰色。 动物用此策略融入到背景中。例如，生活在树上的竹节虫伪装成小木棍。而雪鸮周身覆盖着雪似的羽毛。 2. 模仿是指动物长成其他一些危险的动物，以此吓跑捕食者。一个很好的例子是，猩红王蛇无毒，但全身的颜色和图案类似于有毒的珊瑚蛇。 3. 斑马之类的动物会使用混隐色，它们群居，并具有斑点和条纹等特征，故每只个体都不会太突出。
植物也可以伪装！让我们来看看捕蝇草。平时，捕蝇草的叶子张开，表面呈红色，看上去像一朵盛开的花。当吸引虫子接近，它会迅速合拢叶子困住虫子。
战场上的士兵们穿着大自然的颜色的衣服，保护自己免受敌人的攻击。Alan也喜欢钻进毯子下甚至枕头中，这是他躲避我进行的伪装！感谢您的观看，希望您能喜欢！
