鲸课文原文,全文

不少人看过象,都说象是很大的动物。其实还有比象大得多的动物,那就是鲸。最大的鲸有十六万公斤重,最小的也有两千公斤。我国捕获过一头四万公斤重的鲸,有十七米长,一条舌头就有十几头大肥猪那么重。它要是张开嘴,人站在它嘴里,举起手来还摸不到它的上腭;四个人围着桌子坐在它的嘴里看书,还显得很宽敞。

鲸生活在海洋里,因为体形像鱼,许多人管它叫鲸鱼。其实它不属于鱼类,是哺乳动物。在很远的古代,鲸的祖先跟牛羊的祖先一样,生活在陆地上。后来环境发生了变化,鲸的祖先生活在靠近陆地的浅海里;又经过了很长很长的年代,它们的前肢和尾巴渐渐变成了鳍,后肢完全退化了,整个身子成了鱼的样子,适应了海洋的生活。

鲸的种类很多,总的来说可以分为两大类:一类是须鲸,没有牙齿;一类是齿鲸,有锋利的牙齿。

鲸的身子这么大,它们吃什么呢?须鲸主要吃虾和小鱼。它们在海洋里游的时候,张着大嘴,把许多小鱼小虾连同海水一齐吸进嘴里,然后闭上嘴,把海水从须板中间滤出来,把小鱼小虾吞进肚子里,一顿就可以吃两千多公斤。齿鲸主要吃大鱼和海兽。它们遇到大鱼和海兽,就凶猛地扑上去,用锋利的牙齿咬住,很快就吃掉。有一种号称“海中之虎”的虎鲸,有时好几十头结成一群,围住了一头三十多吨重的长须鲸,几个小时就把它吃光了。

鲸跟牛羊一样用肺呼吸,也说明它不属于鱼类。鲸的鼻孔长在脑袋顶上,呼气的时候浮上海面,从鼻孔喷出来的气形成一股水柱,就像花园里的喷泉一样;等肺里吸足了气,再潜入水中。鲸隔一定的时间必须呼吸一次。不同种类的鲸,喷出的气形成的水柱也不一样:须鲸的水柱是垂直的,又细又高;齿鲸的水柱是倾斜的,又粗又矮。有经验的渔民根据水柱的形状,就可以判断鲸的种类和大小。

鲸每天都要睡觉。睡觉的时候,总是几头聚在一起,找一个比较安全的地方,头朝里,尾巴向外,围成一圈,静静地浮在海面上。如果听到什么声响,它们立即四散游开。

鲸是胎生的,幼鲸靠吃母鲸的奶长大。这些特征也说明鲸是哺乳动物。长须鲸刚生下来就有十多米长,七千公斤重,一天能长三十公斤到五十公斤,两三年就可以长成大鲸。鲸的寿命很长,一般可以活几十年到一百年。
