古希腊神话中有这么一个传说:在古代,动物都没有尾巴,狮子就给大家各分了一条尾巴。其实,这只是古人的想象。
为什么动物有各式各样的尾巴呢?它们的尾巴都是为了生存有利而生成的。
松鼠的尾巴可以让松鼠增加跳跃距离,而且很保险,只有极少数会有意外。松鼠下跳时会张开降落伞似的尾巴,起到平衡和缓冲作用。松鼠睡觉时,会把尾巴盖到身上,这样就像盖了一床被子,十分暖和。松鼠控制尾巴的摆动,以作交流的语言。
狐狸尾巴十分粗壮,毛发尤为蓬松。在冬季,狐狸把自己蜷缩起来,用像围巾的尾巴将自己裹住,可以保暖。狐狸是肉食动物,尾巴可以在它捕食时起到一定的帮助:在狐狸扑向猎物时,可以用尾巴迷惑敌人;狐狸逃跑时,会用尾巴“扫地”,不知不觉就将攻击家禽时留下的血迹“毁尸灭迹”了。
老虎的尾巴也有妙用:可以保持身体平衡。在与敌人搏斗时,老虎会用链条式的尾巴将敌人抽得晕头转向,再发出致命一击。夏天,老虎尾巴可以像牛尾巴那样赶蚊子,在很热的时候,老虎尾巴沾水就能散热。
也许你很奇怪,人为什么不长尾巴呢?科学家们已经有推测了:随着人类进化的发展,大脑越来越灵活,人的尾巴不但没有像松鼠、狐狸、老虎的尾巴那样有很好的作用,反而妨碍人类运动,所以尾巴就慢慢退化了。
几乎所有的动物都有尾巴,它们的尾巴颜色不同,大小不同,形状也不同。
让我们一起看看松鼠、老牛、壁虎、燕子、小鱼、狼、羊的尾巴都有哪些不同之处吧。
松鼠的尾巴最特别,它的身子小小的,尾巴却大大的。它的尾巴用途很大,跳跃的时候可以帮助它保持平衡,跳到高处的时候,尾巴起到了降落伞的作用,冬天的'时候,尾巴可以盖在身上御寒,遇到危险时,摇动尾巴可以迷惑敌人,小松鼠的尾巴还可以用来交流信息,协调行动。
老牛的尾巴细细的、长长的,总是甩来甩去,原来它是用尾巴赶牛蝇。
壁虎的尾巴短短的,可以再生,如果有敌人抓住了它,它可以舍掉它的尾巴逃走,而它的尾巴还可以长出新的。
小燕子的尾巴像一把剪刀,它能在天空中自由自在的飞来飞去,全是那剪刀似的尾巴掌握方向。
小鱼的尾巴很漂亮,像个小花瓣,它的尾巴也是能帮助小鱼游泳的时候控制方向。
大灰狼的尾巴是大大的,而且比较硬,它的尾巴也有控制平衡的作用。
羊的尾巴大多短短的,毛茸茸的,看起来可不起眼,但它却是一个移动的营养罐。
每个动物的尾巴都有自己的用处,你还知道哪些动物的尾巴有哪些用处呢?

我最喜欢的小动物有很多,燕子、小狗、小兔子、小松鼠……这其中,要数我最喜欢的那就是小猫了,说起小猫来,我家也有一只,那么我就来讲讲我和小猫的故事吧。
那只小猫的毛软软的,滑滑的,头上还有好看的花纹,所以,我给它取名为花花花花的胡子很长,有一次我拿爸爸的刮胡刀去给花花刮胡子。妈妈说:花花的胡子不能刮,因为在很暗的地方,她能微微的抽动胡须,才能量出来道路的宽度。哇,原来它的胡子还有这么大的作用啊!我说。
花花非常爱干净,它拉便便也要去上厕所,一个便盆里放了很多煤渣,它每次拉完便便的时候都要用煤渣把便便埋起来。
花花是我的好朋友,每次我有零食都给它分一点,我穿袜子它就在我的脚上蹭来蹭去,我和它一起晒太阳,跟它一起说悄悄话。
这就是我最喜欢的小动物——花花。
There are a lot of my favorite small animals, swallows, puppies, rabbits, squirrels... Of which, the number I like most is the cat, talking about the kitten and my family, so I'll tell about the story of my cat and my cat.
The cat's fur is soft, slippery, and beautiful pattern on the head, so I gave it a name flower flower beard, once I took the razor to shave flower dad. Mother said: the flower mustache can not be shaved, because in a very dark place, she can gently tap the beard, to measure the width of the road. Wow, it turns out that its beard has such a big effect! I said.
Huahua is very clean. It URLs and URLs and goes to the toilet. There are lots of cinders in a bedpan. Every time it pulls out, it uses coal cinder to bury the toilet.
Huahua is a good friend of mine. Every time I have snacks, I want to share it with you. When I wear socks, it will rub on my feet. I will share the sun with them and talk quietly with them.
This is my favorite little animal - flower flower.
