八下保护鲸鱼作文英语【一】
鲸是一种哺乳动物，在我们中国海域有三十多余，其中海豚也是一种。
鲸的怀孕期一般在十二个月左右，也就是一年，一胎一子，而幼鲸的哺乳期为十个月。鲸分为两种类型：一种须鲸，一种齿鲸。
须鲸的体型是非常巨大的，目前已经发现最小的约体长六米，它们是喜欢吃大量的小鱼与底栖贝壳类的。须鲸包括：蓝鲸、长须鲸。
齿鲸的身长最短约三十厘米左右，齿鲸包括：抹香鲸、突吻鲸、白暨鲸……
抹香鲸是一种海洋齿鲸哺乳动物，抹香鲸是在齿鲸中“潜水能王”。为什么它潜得这么厉害呢?因为抹香鲸的头部里含有一种特殊的“鲸脑油”，它可以提供，使鲸脑油不受冷凝固，脑袋体积是缩小，身体就会膨大之后，它的红蛋白的储氧量大，皮肤厚实紧密、富有弹性，脂肪厚在深海可以靠鲸脂保暖背肌。所以这就能从海洋上潜这么深的原因。
虎鲸也是一种齿鲸哺乳动物，它的身长约八至十米，体重约九吨。它的头部圆溜溜的，皮肤是黑白相见的。体型又圆又肥，总得来说真的好可爱，为什么呢?大家都认为虎鲸是很凶猛的，怎么能说是可爱呢?因为我觉得它的体型像一个黑白相见的气球一样!当然我说的是体型，但是实际上的虎鲸攻击力很强的，也就是说：我看到谁是我打得过的，那一定就是我的食物，打不过的我就装作不知道。所以，这就是虎鲸的性格!
蓝鲸是须鲸的一种，身长约三十米，体重重达一百八十一吨，它的身躯瘦长，背部是青灰色的。蓝鲸每天要喝很多水，它的喝是一大口一吸就喝进去了，但是它也要过滤的，这样水与食物就分开了。所以，人们常常看到的蓝鲸喷水就是因为这个!
最后，鲸的亡就称为“鲸落”，当鲸去之后，尸体最终沉入海底，一座鲸鱼的尸体可以供养一套以分解者为主的循环系统，长达百年。
同学们听我讲解了这么多，你们明白了吗?

Tiger is one of the most valueable animals to human beings today. It is somehow like a cat, but much bigger than it. It lives in the forest, and feeds on small animals.
Nowadays, the number of the wild tiger is becoming small and small. Maybe there will be no tiger any more if people continue cutting the trees, destorying the living environment or hunt the tiger just for the skin. We must stop all these mistakes. We should protect them, because the world without tiger is not a completed one.

大家好！新年快乐！我是只鲸。你知道我吗？要知道，我可是世界上最大的动物！如果有什么动物比我还大的话，那我敢肯定，那是外星动物！我的体重也很重耶！你知道是多少吗？说出来你别晕！十三万公斤！你信吗？不过我就是这么重，谁让我身体这么庞大。对了，我有一位爷爷，他可是鲸鱼家族里的元老了，体重有16万公斤！他的体重是目前世界上最重的。我还有一个妹妹，他才三岁，但体重也有三千多公斤。
我的名字叫鲸鱼，其实我更本不是鱼类，我是哺乳动物。只因为我生活在海洋里，体形像鱼。其实，在很久很久以前，我的祖先们都生活在大陆上。过了一段日子，海洋向我们祖先生活的大陆侵袭过来，陆地有一部分被海洋淹没了，我的祖先们只好生活在靠近陆地的浅海里；在不知不觉中，他们的前肢和尾巴都变成鳍了，真是可怜，他们的后肢就那样消失了，整个身子变成鱼的样子。后来他们只好到海洋里生活，没想到，他们还真的适应了海里的生活！
我们鲸分为两类，一类是须鲸，还有一类是齿鲸。我呢？嘿嘿！就是齿鲸。我非常能吃的。我最喜欢吃大鱼和海兽了。我看见有大鱼游过来，趁他们不注意，扑上去，猛咬一口，嘿嘿！他们就玩完了！休想从我嘴中逃脱！瞧！那边有一个大鲨鱼过来了，哈哈，我饿急了。鲨鱼游过来了，我马上扑过去，一口咬着，鲨鱼一声惨叫，还在挣扎，嘿嘿！他哪里逃得掉。我锋利的牙齿一下子就把它给“咔嚓咔嚓”了。嘿嘿嘿嘿！对了，我还有一个表哥，它叫做虎鲸，号称“海中之虎”，他比我猛多了，经常吃须鲸，有一次他和伙伴们聚在一起，围住了须鲸，分别向它扑上去，大口咬着，三十多吨重的须鲸他们几个小时就“咔嚓咔嚓”了。厉害吧！还有一类是须鲸，他们没有牙齿，他们吃的时候就把嘴巴长大大的，向前游着，把小鱼小虾连同海水吞进肚子里，然后再把海水从须板里过滤出来，把小鱼小虾吞进肚子里，不过这样吃不够过瘾，要吃好几千公斤才能吃饱。
由于我是哺乳动物，所以我要用肺呼吸。你知道我的鼻孔在哪吗？说出来你别下一大跳，它长在我的脑袋上。所以我呼吸的时候要浮出海面，从我的鼻孔里面喷出“喷泉”好壮观哦！不过我的“喷泉”没有须鲸的“喷泉”好看。我的“喷泉”又粗又矮，倾斜的，而须鲸的“喷泉”总是垂直的，又高又细。
不过现在有好多人都在大肆地捕我们，把我们的肉卖掉，把皮剥下来，把脂肪做油和肥皂。导致我们鲸家族大部分都灭亡了。
因此，我今天在这里郑重宣告一声：人类，请不要再捕我们了！如果你们再执迷不悟。我们商量好了，过几年后再次跑到大陆上，把你们人类也给“咔嚓咔嚓”了！我希望我们友好相处！
